-Vehicles- Hopefully even the mighty AT-AT could be made deployable by the commander.

Seriously, though, I wouldn't mind this done, if it's implemented in a good way.
-Defense shields- small, but big enough to cover a cp these shields would deflect any bombardment for a given period of time. Would give grunts a fighting chance until reinforcements arrived. This could also be done by an engineer class if not by commander.
I loved the deployable shield in Galactic Conquest. Deployed by the Engineer and shaped like a half-dome, so that if you put two down (which required two engineers), you had an actual dome you could hide under. It was about three meters wide and two meters tall, and deflected laser bolts, although grenades and other non-laser objects went straight through it. Infantry could pass through the shield, but took damage doing so, similar to when they went through barbwire in Vanilla.
I loved the camouflage tent, too, when I think about it. Little thing you deployed and hid under, and that you could see out of and fire through. Was actually pretty hard to spot, especially if you didn't know what to look for, in which case I can imagine it'd just be an oddly shaped terrain feature not worthy your ammo, until it started shooting at you.
