Hi, i am a long time lurker, first time poster, i am currently in Iraq serving in the Army as an 88M. i am in a PLS company that has a primary mission of Gun Truck security here in Northern Iraq.
If they had two steering axles and three pull axles they were PLS trucks.
PLS trailers have one steering axle and two rear axles. (if fading memory serves me)
HEMMETs have four axles.
just wanted to clarify:
M1074/M1075 PLS (Palletized Loading System) Tractors (just the truck portion without a trailer) have 3 steering axles (numbers 1, 2, and 5) and 2 pusher axles (numbers 3 and 4). they also have a LHS System (Load Handling System).
M1120 LHS Tractors (just the truck portion without a trailer) have 2 steering axles (numbers 1 and 2) and 2 pusher axles (numbers 3 and 4). they also have a LHS System (Load Handling System) from which they take their name.
HEMMETs (in all its versions) have 2 steering axles (numbers 1 and 2) and 2 pusher axles (numbers 3 and 4). they do not have a LHS System (Load Handling System).
M1076 PLS Trailer has 1 front steering axle and 2 rear coaster axles
just thought i would put that out there, hope i did it in a manner as not to offend
