Ground units to add to the "unarmed" category

[Tom P]

Probably not as popular but some non combat vehicles would add to the realism and emersion to the digital battlefield. These are modern US vehicles since that's what I know. Maybe someone else can chime in as well for other countries. 

As a mission maker I would 100% use these. 
Medical: 
M997 Field Litter Ambulance (FLA) medical hmmwv
M133 Medical evacuation vehicle (MEV) medical Stryker
Bonus (not a ground unit but on the topic of medical)
UH-60L or UH-60M Medevac AI. Possible reskin of the current in game 60A. Or just reskin the 60A since it's dated.

Support:
M88A2 "Wrecker" Armored Recovery Vehicle. Essential in armor units, Abrams, Brads for example.
M984A4 "Wrecker" Recovery Truck. LMTV version, used practically in all units with vehicles, HMMWV, Strykers for example.

Other:
M1117 Armored Security vehicle. Mainly used by military police, common at check points. 
M149A2 AKA the water buffalo. Heck yes.
