You can kill with grenades just fine without a UAV droid.

I disagree with limiting troopers. The trooper is just that- a trooper, the backbone of the army. The team should be mostly comprised of them. I think making each class more specialized would help. Troopers are the main and most efficient way to take out infantry. Heavy Weapons are specialized to deal with armour but have little anti-infantry capabilities. Support should be about support,(and now that I think about it, repair AND resupply makes sense) like resupplying, repairing a minimally effective anti-infantry weapon. Medic should focus on healing, reviving, and bio-chemical warfare. Also a minimally effective anti-infantry weapon.

Basically, BUFF the TROOPER;s ability to take out infantry, and the HEAVY WEAPONS SPECIALIST's ability to deal with armour and other defenses. NERF the SUPPORT's and MEDIC's ability to kill, and BUFF their ability to do what they're specialized in.

As for the officer, he should be less focused on fighting, and more on leading. Squads should be DEPENDENT on the officer.

Lemme see...I'll do some research and see if I can come up with more ideas.

You're thinking almost on the same line's as me, TIEPilot. Brilliant minds and all that!

I would adjust your list like this:

SUPPORT TROOPER:
*Melee Weapon
*Light Repeating Blaster/EMP weapon
*Pistol
*EMP Grenade (2)
*Generator (Resupply)
*Portable Shield Generator (1)(Pick-up, Redeployable)
*IT-O Droid

Engineer Specialist (formerly Heavy Weapons):
*Melee Weapons
*Anti-Armour Weapons/Mortar Guns/Deployable Heavy Repeating Blasters
*Pistol
*Fusion Cutter (Repair)
*Anti-Vehicle Mine (3)
*DetPack (3)
*Repair Droid

Mmm... vanilla!
