“Fire in the hole! Fire in the hole! Fire in the hole!”
The last radio call a Marine detonating an improvised explosive device makes to Marines on the other side of the soundwaves outside the danger zone of an oncoming blast.
One, two, three seconds – then instantaneously – a sound like thunder rings through the dense Okinawan jungle.
The shockwave lifts the ground, shakes concrete bunker walls, and pulses through the center of ones chest.
As the sound of the explosion vanishes into the air, Marine Explosive Ordnance Disposal technicians and Okinawa Prefectural Police patiently wait 45 seconds for any debris or shrapnel from the blast to return to earth.
