Ok, here goes.
Lead hummer: 12d6.hits(5)=4
It's a standard old school Hummer, the gunner draws some interest. You can make out a unit insignia "Unit 9" you recall something about a force called the Unit, and section 9. They were a group that was used for covert operations, specializing in extracting sensitive material.
GMC MPUV: 12d6.hits(5)=3
This vehicle you've seen many times, but the new Smart armor plating makes you wonder that is the kind of stuff meant for the battle field not some OP in a city.
Chase hummer: 12d6.hits(5)=6
This one you get a good deal of info, the turret is a MK4 mobile unit that's meant to be used as a sentry gun outside a forward operations base, usually controlled via rigger or hacker. That means they might have matrix support.
Drone: 12d6.hits(5)=5
An older drone, but you've seen them used for over watch before but the fact it has a chameleon coating makes you wonder you thought this was an older drone that would have been retired.
And, just in case,
Stoner Ares M202: 12d6.hits(5)=1 (no glitch)
Just a standard mounted gun.
