1
Vietnam, January 1967.
2
The U.S and its allies have dropped more bombs on this region
3
than they did on Germany and Japan combined during World War II.
4
But the Viet Cong are safe.
5
Hidden beneath the ground is a tunnel network that spans over 100 kilometers.
6
At the entrance is Tommy Rivera.
7
His mission is to avoid the deadly traps and enemy soldiers, locate the control room, and gather intel to stop the Viet Cong's next major attack.
8
If he fails, hundreds of American soldiers will die.
9
Tommy climbs into the tunnel, covers the trapdoor with leaves, and closes himself inside.
10
With a casualty rate of over 30%, most tunnel rats don't survive their second mission.
11
Tommy is equipped with the standard issue M1911.
12
But in these tunnels, it's more of a liability than a weapon.
13
A single shot could alert the enemy.
14
Instead, he trusts his father's old World War II knife.
15
Quiet, reliable, and deadly in close combat.
16
Tommy doesn't know it yet, although he is getting very close to the first chamber.
17
Based on Tommy's previous missions, he is expecting a similar layout.
18
Connecting to the entrance, there are three levels of tunnels.
19
Tommy is in the first level, the entrance is where the Viet Cong can quickly hide away in case they are being attacked.
20
The deeper he goes, the closer he gets to the main living and operations hub.
21
This includes hospitals, sleeping chambers, and his target, the command center.
22
At the very bottom is the Viet Cong's safest area built for emergency situations.
23
Bomb shelters, evacuation tunnels, interrogation rooms, and water wells.
24
Tommy creeps forward, taking short, shallow breaths to keep as silent as possible.
25
His nose picks up a faint smell of rusty metal.
26
The first room is near.
27
Suddenly, he spots something ahead.
28
A thin bamboo trigger.
29
Above in the ceiling is a small camouflaged panel.
30
Something's moving behind it.
31
Its heart races.
32
Vietnam Pit Vipers.
33
Each tunnel system can hold more than 50 unique traps.
34
Some explode.
35
Some impale.
36
Some release toxic gas.
37
This one is designed to cause organ failure and internal bleeding from the venom.
38
If Tommy touches the bamboo, it will send a signal by pulling out the toggle, causing the wooden panel above his head to swing open and the snakes will be released.
39
Most soldiers turn back when they see what lies ahead, but Tommy can't.
40
Thousands of lives depend on him finding the Viet Cong attack plans.
41
He grips the dirt and starts to move.
42
One elbow forward, then the next.
43
He slides above the trigger.
44
Three, two, one.
45
And he's clear.
46
But these traps only get more deadly the deeper he goes.
47
This is just the beginning.
48
The more Tommy crawls, the stronger the smell becomes.
49
The narrow, dirt tunnel curves slightly to the left, then opens.
50
He's reached the first chamber.
51
Just four feet wide and five feet tall.
52
This cramped design is not by accident.
53
Viet Cong soldiers averaged just five feet three inches tall, while American soldiers Stood around 5'9".
54
That height difference made it nearly impossible for most Americans to fit inside.
55
But standing at 5'1", Tommy is perfect.
56
Low wooden crates stacked against the wall holding ammunition, medical gear, and rice.
57
Storage was frequently placed near the entrances allowing the Viet Cong to restock or retreat faster during battle.
58
He listens for a moment to hear if anyone might be nearby.
59
Silence.
60
Tommy pushes forward.
61
The soil down here contains high levels of clay and iron.
62
When it dries, it develops concrete-like properties, stopping the tunnel from collapsing.
63
However, while it's raining, there's still a risk.
64
After several more minutes of crawling, he reaches the entrance.
65
This chamber is larger.
66
The far end is a shallow pit.
67
It's a huang kham stove.
68
This is where they cook.
69
Unlike the Americans who had supply chains stretching from aircraft carriers to jungle outposts, the Viet Cong had to scavenge, barter, or steal their food.
70
To cook and breathe, they built ventilation shafts from the tunnel ceilings to the jungle floor, disguising them as termite mounds.
71
But cooking releases smoke.
72
If the Americans saw it rising from the ground, their location would be compromised.
73
Stay hidden.
74
They only cooked meals during the morning or when it's raining, so the natural fog would Tommy squats down.
75
A few pieces of rice still cling to a crusted pot.
76
The embers are still warm.
77
Someone was just here.
78
His pulse quickens.
79
Back home, on the news, Tommy constantly heard about America's success, high body counts, and tactical victories.
80
But when he arrived in Vietnam, the reality felt completely different.
81
Everything seems stuck with no real progress.
82
That's because he had only been told one side of the story.
83
The kind of bias you won't fall for if you read ground news.
84
They pull data from over 50,000 sources worldwide, letting you see how different outlets frame the same story, so you can compare perspectives, form your own opinion.
85
In Taiwan, news broke that the country is updating its air raid protocols, drawing lessons from Ukraine and Israel to protect civilians in the event of a Chinese invasion.
86
Over 20 outlets have covered this story, with coverage split evenly across the political spectrum.
87
But side by side, the contrast is clear.
88
The left-leaning headline focuses simply on what Taiwan can learn from Israel, while the right-leaning one digs into how the new protocols will be implemented with its citizens.
89
If you want to take back control and see what everyone else can't, Ground News is giving you the tools.
90
Right now, they have a huge 40% off the Unlimited Access Vantage plan.
91
But the sale is ending soon, so go to ground.news.atrium or scan the QR code before it goes.
92
The enemy is nearby.
93
There is no time to waste.
94
Tommy hopes that this next room will be the command center, so he can get back to base and sit by the warm fire.
95
He keeps crawling.
96
Then, the ground begins to slope downward.
97
He pauses.
98
He knows exactly what that means.
99
He's entering level two.
100
The deepest levels are where the real secrets are hidden.
101
Surgery bays, weapons workshops, supply caches, and his target, the command center.
102
The air becomes thicker but sterile in a way that's unnatural for a tunnel.
103
Then he hears it.
104
Movement, soft and muffled.
105
Tommy freezes.
106
The sound echoes faintly down a tunnel to his right, shuffling.
107
A whisper of voices too quiet to make out.
108
They don't know he's here.
109
Tommy clutches his knife.
110
He waits and listens intensely, but the sound starts to fade.
111
False alarm.
112
As he approaches the next room, he sees a glow of light.
113
A bed is pressed against the wall.
114
Next to it, a stack of blood-stained bandages and scissors.
115
Glass jars lined along a dugout shelf.
116
In the corner is a bicycle-powered generator.
117
This is a quiet way to generate electricity to light this hospital room during surgery and charge their radio equipment.
118
Only found in the more developed systems, a faint tapping sound echoes through the chamber.
119
Tommy goes still.
120
He knows that sound.
121
They are digging.
122
At the start of the war, the Viet Cong would dig during the day, making it easier for Americans to locate them.
123
However, now they only do it while raining or at night when the jungle sounds overpower their own.
124
Others would be nearby, hauling dirt in baskets up to the surface.
125
Every handful is carried far from the tunnels, scattered across fields, buried in bomb craters or dumbs into rivers into rivers.
126
The surface will be crawling with Viet Cong.
127
Tommy hopes the rain stops soon, otherwise his escape just got a lot harder.
128
Still, not all news is bad.
129
Medical rooms like this one are almost always placed on the second level, the same level as the command center.
130
He's close.
131
Very close.
132
The tunnel tightens again.
133
Tommy claws forward, the walls pressing in, his nails scratching in the dirt, until the path opens.
134
He stops.
135
This isn't a storage room.
136
It's something else.
137
He tries to see what's inside, but it's too dark.
138
He knows using his flashlight could expose him, but staying blind could kill him.
139
He has no choice.
140
He flicks it on.
141
What he sees makes his blood run cold.
142
It's the trap room.
143
Most designs weren't meant to kill.
144
They were made for one purpose only, to make soldiers like Tommy hesitate.
145
To make them afraid of the floor, the walls, everything.
146
11% of combat deaths are caused by the tens of thousands of booby traps deployed by the Viet Cong soldiers.
147
In the corner, a pile of bamboo, each stake sharpened to a deadly point.
148
Tommy remembers the last time he saw one above ground.
149
A fellow The soldier stepped on a false floor.
150
The scream was brief.
151
The pit was full of spikes.
152
Sometimes the tips are even smeared with feces.
153
Not to kill instantly, but to infect, to rot from within.
154
He turns.
155
In another area, a stack of tin cans.
156
But it's not harmless junk.
157
Inside are grenades, rigged with trip wires.
158
Pull the wire, the pin yanks free.
159
Boom.
160
Through decades of fighting off foreign powers, the Vietnamese have learned to use the land to kill any invader.
161
With a reminder of death, Tommy cuts his light and presses forward into the dark.
162
He hears a faint sound and freezes.
163
It's coming from ahead where the tunnel forks.
164
On his left is a subtle echo of voices.
165
Viet Cong, at least two, maybe more.
166
To his right, silence.
167
But Tommy knows what silence can mean down here.
168
A dead end, or worse, a trap.
169
His heart thuds.
170
The left tunnel could put him face to face with the enemy.
171
The right could be a trap, ending his life and the mission.
172
He waits, motionless, counting his breaths.
173
The voices grow clearer.
174
Calm, casual, too calm.
175
That's what scares him.
176
He shifts his body toward the right tunnel, elbows dragging through the dirt, hips twisting.
177
Each breath he takes could be his last.
178
No wire, no pressure plate.
179
Not yet.
180
Five feet in, still nothing.
181
Then the tunnel opens slightly, just enough for him to kneel.
182
He is safe, for now.
183
It's the second time luck is on Tommy's side.
184
Deep down, he knows it won't last forever.
185
And that's when he sees it.
186
Ahead, lit by only the faintest glow from the lantern, is a large room, reinforced with timber,
187
large maps pinned to the wall, chalk markings, folded documents.
188
This isn't another survival chamber.
189
This is his target, the command center.
190
Tommy scans the area.
191
There's no one inside.
192
He moves in silent and low.
193
The crude table at the center holds an unfolded map.
194
A red line stretches west towards Saigon.
195
Circles, notes, arrows, targets, highly classified materials.
196
Somehow, the Viet Cong have secured info about an upcoming offensive.
197
This was more than just the attack plans he came for.
198
When Tommy left the camp, they were preparing for this very operation, including some of his closest friends.
199
They spoke with quiet hope, a final push that could end the war in weeks.
200
But now he realizes none of them knew the truth.
201
It wasn't a breakthrough at all.
202
It was an ambush.
203
If Command sees this, they can call off the advance and change course.
204
This isn't just another mission.
205
It's personal.
206
Failing to get back to the base doesn't just mean helping to defend their base, it means saving his entire platoon from a certain death.
207
Tommy hears noises again.
208
Closer now.
209
The longer he spends in here, the more likely he is to be caught.
210
He needs to find the military base attack document.
211
He looks over to see some rolled up papers.
212
Without enough time to look inside, he straps them under his belt.
213
Now, he has another problem to worry about.
214
How does he get out of here?
215
As Tommy turns to crawl back the way he came, he hears shuffling.
216
Close.
217
Tommy grabs his knife, back pressed against the wall.
218
He won't use the gun, as it will alert the entire tunnel system, making his escape so much harder.
219
The shuffling grows louder.
220
As the Viet Cong soldier's head enters the room, Tommy strikes.
221
The man collapses.
222
Tommy doesn't move.
223
He listens in case anyone has been alerted.
224
It's a young Viet Cong soldier.
225
He flips the body over, quickly patting down his vest.
226
A knife, loose ammo, some rice wrapped in a banana leaf.
227
A picture of the soldier and his family.
228
He can't be much older than 16, although that was a couple of years ago now.
229
So much has changed since then.
230
Many of the Viet Cong soldiers started young, raised in the dark, trained underground, pardoned by a war that offers no childhood.
231
At this point, nearly 400,000 dead.
232
Many of them are civilians.
233
Nobody down here really wants to fight.
234
They just don't have a choice.
235
Tommy finds something else.
236
A folded piece of paper, wrapped in plastic to keep it dry.
237
A hand-drawn map showing a rough outline of the tunnel system.
238
He identifies his location.
239
Then, another symbol near the way out, closer to the surface.
240
With limited Vietnamese, he makes out the word prisoner.
241
If someone's still alive down here, he can't leave them to die.
242
Out here, the Americans have a code.
243
No man gets left behind.
244
Still, it could easily be a trap.
245
The Viet Cong often turn this against them, turning prisoners into bait.
246
Tommy tucks the map into his chest pocket, grabs the Viet Cong's body, and hides it in the corner of the room.
247
The mission just got much more complicated.
248
In less than 10 minutes, someone will find the body, and when they do, Tommy will still be in the tunnels.
249
If he's going to free this prisoner, Tommy's going to need to fight.
250
Guided by the map, he takes a hard turn down the new passage.
251
The air grows colder, the floor angles sharply downward, his knees scrape and boots slip.
252
The tunnel continues to twist deeper into the earth than anything he's ever encountered.
253
Whoever this prisoner is, they must be important.
254
No one gets buried this deep without a reason.
255
As Tommy rounds the last bend, he hears something.
256
voices, not footsteps, but breathing.
257
That's when he feels his elbow hit a string.
258
This pulls a cord directly attached to a pin.
259
He closes his eyes.
260
This could be the end.
261
A piece of string with metal scraps is attached, which is propelled toward a metal bell, making a loud clang.
262
It's a noise trap.
263
His heart pounds.
264
They know.
265
Tommy exits the tunnel into the room.
266
A figure hangs from a bamboo pole lashed into the wall.
267
An American.
268
The soldier's uniform is shredded, blood on his face.
269
He lifts his head weakly when he sees Tommy, but doesn't react.
270
He's too dehydrated and malnourished, but alive.
271
Tommy moves in and quickly pulls the gag loose.
272
Don't speak, he whispers.
273
You're gonna be okay, but we need to leave now.
274
He draws his knife and slices the rope and lowers him down.
275
The soldier winces, but doesn't cry out.
276
He's light.
277
Tommy stops.
278
Tommy checks the map again.
279
There's an exit nearby, up above.
280
Viet Cong soldiers will know they will be looking for the fastest way out and will be planning to intercept them.
281
They know too much to be allowed to escape alive.
282
Tommy tells the soldier to stay close.
283
He puts the map away, tightens his grip on his knife, and starts to climb toward the surface.
284
The rescued soldier stumbles behind him, barely able to keep pace.
285
Tommy keeps an ear on the tunnel behind them.
286
No sound, yet.
287
But it's coming.
288
Every corner they turn, every shaft they crawl through, Tommy expects movement, a voice, a shot.
289
Turns around and helps pull the soldier up a steep incline.
290
Light leaks faintly from above.
291
An exit?
292
Behind them is a voice, shouting.
293
They've been spotted.
294
Tommy doesn't wait.
295
He pulls the soldier harder and pushes forward up the slope, toward a narrow beam of light.
296
Then, gunfire.
297
Bullets ricochet against the walls.
298
Dirt sprays behind his head.
299
Another shot.
300
He reaches the top.
301
A bamboo hatch.
302
He reaches out to open it.
303
Locked.
304
He slams his shoulder into it once, twice.
305
It cracks.
306
Sunlight floods in.
307
They're not safe yet.
308
He grabs the soldier under the arm.
309
They start running.
310
No clear direction, no cover, just raw instinct and the will to survive.
311
Behind them, Viet Cong soldiers spill out from the bamboo hatch, weapons raised.
312
Bullets crackle through the trees.
313
Tommy doesn't look back.
314
Branches slice their faces.
315
Every step is a gamble.
316
But every step is further from danger.
317
He glances up.
318
Smoke trails in the far distance.
319
A campfire?
320
A signal?
321
Hope.
322
It might just be okay.
323
The Vietnam War stands as one of the most brutal and arguably most pointless conflicts in modern history, lasting over 19 years.
324
The suffering it unleashed was huge, healing an estimated 5 million human lives from America, Vietnam, Laos, and Cambodia.
325
Within war stories we find heroes, like Tommy Rivera, but a deeper question must be asked.
326
What exactly is the hero fighting for?
327
Throughout history, information has convinced us that heroes fight for their country and their people.
328
But too often, they're fighting for something else entirely,
329
a political machine, where corporations profit by selling weapons to governments under the disguise of patriotism.
330
By 1968, 54% of Americans believed the Vietnam War was a mistake, yet dragged on for another seven years.
331
It's not just history, it's a pattern.
332
The next time you see a war taking place, take a moment to think, is this war everything it's claimed to be?

シャドーイングとは？英語上達に効果的な理由
シャドーイング（Shadowing）は、もともとプロの通訳者養成プログラムで開発された言語学習法で、多言語習得者として知られるDr. Alexander Arguelles によって広く普及されました。方法はシンプルですが非常に効果的：ネイティブスピーカーの英語を聞きながら、1〜2秒の遅延で声に出してすぐに繰り返す——まるで「影（shadow）」のように話者を追いかけます。文法ドリルや受動的なリスニングと異なり、シャドーイングは脳と口の筋肉が同時にリアルタイムで英語を処理・再現することを強制します。研究により、発音精度、抑揚、リズム、連音、リスニング力、そして会話の流暢さが大幅に向上することが確認されています。IELTSスピーキング対策や自然な英語コミュニケーションを目指す方に特におすすめです。
