How a US Sniper's 'Wire Trick' Silenced 16 Japanese Bunkers in 30 Minutes on Iwo Jima

Experience the Pacific War like never before with restored WW2 In Color footage.

Witness the vivid reality of Iwo Jima through colorized archival film as we analyze the impossible feat of PFC Douglas Jacobson. Originally a B.A.R. gunner, Jacobson was thrust into the role of an anti-tank specialist with zero formal training on the M9A1 bazooka. Yet, he achieved what conventional doctrine deemed impossible.

Operating alone—without a loader, air support, or the standard platoon-level backup—Jacobson used precision geometry and unconventional tactics to dismantle the reinforced defenses of Hill 382.

📺 In This Colorized History Breakdown:

The Impossible Mission: See how Jacobson cleared 16 bunkers in just 4 hours and 16 minutes—a task doctrine stated would take four platoons and 16 hours.

The Enemy Defenses: Explore General Kuribayashi’s "honeycomb" network: 21,000 defenders, 18km of tunnels, and concrete walls 60cm thick designed for maximum attrition.

The Weaponry: A deep dive into the M9A1 Rocket Launcher (Bazooka). Learn how Jacobson used carpentry math to compensate for the weapon's limitations against 15cm firing ports.

📊 Tactical Analysis & Ammunition Log:

Rockets Deployed: 11 M6A3 rounds against fortified positions.

Tactics: Use of fragmentation grenades and pistol rounds for close-quarters clearance.

Outcome: 75 enemy soldiers neutralized and zero friendly losses in his immediate sector.

🎖️ The Legacy: Jacobson’s actions didn't just earn him the Medal of Honor from President Truman; they rewrote Marine Corps training manuals. This video reveals how his adaptive use of "civilian math" and individual initiative changed bunker protocols forever.

Why Watch in Color? Seeing the volcanic ash of Iwo Jima and the visceral reality of combat in color transforms this from a history lesson into a witnessing of events. It highlights the terrain challenges and the sheer scale of the obstacles faced by the 4th Marine Division.

Recommended for: Military history enthusiasts, WW2 researchers, tactical shooter fans, and anyone fascinated by how geometry and courage can redefine warfare.
