About the UAV Droid:
It's only useful if you want to attack.
If you want to camp, it is stupid to deploy the droid because he gives away your position to easy (remember, the droid hovers over you !).
If you want to camp, it's more sensible to drop the homing beacons in front of you and wait behind them...

IMHO the trooper class should be an attack class, not a defensive camper class.
So remove the homing beacons, and let the UAV Droid stay...

Removing the UAV Droid because it allows a trooper to avoid an ambush if the trooper use the droid ?
What's how it suposed to be. Troopers should attack, and if they should attack they must have the ability to check for an ambush. Without this ability the Trooper will simply refuse to go out for an attack, and set up an ambush...

Officer Kit:
The spawn beacon is not redudant.
Without the beacon the Squadleader must play more careful, with deployed beacon he can change the class and attack.

It's ironic: a small squads can't use the beacon, so the squadleader can't fight:
2 Player Squad = Squadleader can't fight = 1 Player attacking, Squadleader hiding
3 Player Squad = Squadleader can't fight = 2 Player attacking, Squadleader hiding
4 Player Squad = Squadleader can't fight = 3 Player attacking, Squadleader can attack after Beacon is deployed...

So in a 3 Player Squad the officer can't use the beacon and should hide, leaving oit to the other 2 Players to attack.
In a 4 Player Squad the officer can use the beacon, and after rearming (kit change) the officer can attack...

The Scanner of the officer isn't also redundant. A small squad without troopers has no uav.
Small Squads without troopers can still be effective, if the squad is defensive.
Example: Squad of 3 Troopers:
Officer, Heavy, Support
Effective in defense, but no scanners because no Trooper. But the Officer can use his scanner to scan, avoiding to being outflanked.

So, possible alternatives:
Create an AI Commander.
This AI Commander has nothing else to do than to accept a squadleaders UAV Request, so no big AI is needed.
In game the UAV is marked by a probe droid, circling in the sky above the target.

Remove the Troopers UAV Droid & homing becon and the Officers Scanner.
pro:
-Players laying in an ambush are warned by the circling droid above the
-only Squadleaders have UAV

con:
Without the troopers UAV Droid camping is better than attacking.
