Ordnance Corps: 69th Maintenance Battalion. (Heavy equipment/Direct Support) Our motto was 'Rapid Repair And Return'. Unofficially it was 'If We Can't Fix It, F(orget) It'.
We used Transportation Corps heavy lift vehicles and drivers. Everyone else was our folks including escort vehicles modular armored MUTTs and 3/4 ton trucks, and small load trucks (up to duece and a half).
That was for road convoys. Also flew Air Cav and Trans Corps choppers, even Air Force birds a time or two, out of TWA (Teeny Weenie Airport) at Cam Ranh; used Swifties and Navy to move stuff by water; etc.
I even snagged ride on a black C-130 with a million antennas on it to carry some stuff from Ban Mi Thuot back to Can Ranh. Rode the flight deck on that one and was instructed by a guy in a Hawaiian shirt to talk to no one on the flight, or about the flight. Hope the statute of limitations has run out on that by now.
If I could have I'd have commandeered that stinking little plantation railroad north of Cam Ranh, but it didn't go anywhere. Didn't work anymore anyhow.
Hauled supplies out, (everybody's: QM, OrdC, Trans, Meds, anything that was going our way, we took it. Even ran 105mm and 155mm gun tubes, hydraulic fluid, batteries, etc to Marines out in injun country by chopper. Took them 25 gallons of highjacked ice cream one time. They wanted to build a statue to remember us.
) and busted stuff back. Shipped that out of Vung Ro back to Okinawa for rebuild, cannibalization, and/or scrap.
