[58] One 105mm howitzer on 881S was also destroyed.
[59] Not every artillery round that left Khe Sanh was high explosive. During March, Lieutenant Colonel Hennelly's battalion had accumulated more ammunition than it could safely store. Since the ammo would not fit in the berms and presented a hazard above ground, the decision was made to fire it all. This excess included some 90-odd rounds of green smoke. On 17 March--St. Patrick's Day--the Marines fired all the green smoke rounds on known enemy positions to honor the patron saint of the Fighting Irish.
[60] Tanglefoot, as the name implies, is a barbed wire entanglement that is stretched low to the ground and is usually used between larger barriers. Concertina comes in rolls which are laid side by side or on top of each other. Double-apron obstacles are simply barbed wire fences in depth.
[61] To rub salt into the wound, the Marines devised a red flag--Maggie's Drawers--like the ones used on rifle ranges to signal that the shooter had missed the entire target, and waved it every time the sniper fired.
[62] To keep the North Vietnamese from zeroing in on his communication bunkers, Colonel Lownds ordered that fake antennae be placed on every structure at Khe Sanh--including the four-holers.
[63] The ASRT-B radar antennae sustained over 200 hits from shell fragments but continued to function near maximum efficiency throughout the siege.
[64] A conex box is a large metal container primarily used to sea-lift cargo.
[65] Kit Carson Scouts were enemy ralliers who scouted for the Allies.
[66] The pilot was badly burned in the crash and died that night.
[67] Gunnery Sergeant John Basilone was a Medal of Honor winner in World War II. During an action at Edson's Ridge on Guadalcanal, Basilone's machine gun section fired over 26,000 rounds in one night and helped break up a fanatical Japanese attack. Manila John was later killed on Iwo Jima.
