I left in 2011. In my last years a number of HOEU Loadmasters had been trained as instructors for the Precision Airdrop System (PADS). They were presented with an instructors badge. (I have one without the "Instructor"). The HOEU was a AWC Unit. PADS was essentially a carry on computer system hooked up to UHF Radio which would compute the Calculated Air Release Point (CARP) from GPS position data from dropsodes which were dropped on a first run. There was always a desire to integrate this with JAMPA but that was too difficult back then. There is a Youtube video of the system in use at night in Afg. I would guess that things have moved on somewhat since then. Certainly the Loadmasters were doing more than making tea and handing out white boxes to the Drivers Airframe.
