Some more stuff with probably very limited appeal, sorry - some "convoy" stuff.
First up a Barge Carrier based on the USMC LSVR / US HEMTT (to "complete" the "set" lol):
I can't be the only person to do "convoy" style scenarios (can I?) so a Gun Truck is always a welcome addition!
The M985 HEMTT armoured "Gun Truck":

This one has a GMG in the cab position, a twin .50 in the tail and 2 side mounted .50 cals.
Last, for now, the C-RAM Centurion land based CIWS:
Attached, as usual, .Zip file contains 3 icon .bmp, .Lbm of gun truck.
