can't "in" and "outside" be judged from distance to surface above? i.e. if it's big (skybox above) you're outside, small (ceiling) - inside?

And as to the shortlist of tasks, the bot assigned the task needs to be able to perform it. IE they can't throw the grenade if they don't have one, but that's sorta elementary, I guess.

My definition of squad behaviour, at least in the real world:

A group of people of diverse roles who stay within close communication range, provide support for each other in contacts, and recieve orders as a group from a superior.

Possible roles, which may be mixed and matched depending on squad size (i'm still in RL mode here, so it will probably need changing for FPS use), with suggested weapons:
Leader (M16)- In charge of squad (1)
Sniper (M29 Sniper) - expert at long range warfare, (2)
Machinegunner (M249) - self explanitory(3)
Grenadier (M4A4 M203, Frag grenades, smoke grenades) - self explanitory (4)
engineer (M4 or MP5) - demolitions, repairs, driving, disarming/setting bombs(4)
medic (M16, medikit) - self explanitory (5)
communications (M16, commlink) (1)
Scout (MP5SD) - expert in sneaking forwards to locate enemy positions(2)
Rifleman (M16) - general soldier type (5)
RPGman (M4, SMAW) - carries bazooka/anti-tank weapon(4)

Possible combinations for a 5-man squad are show in brackets. add extra rifleman/grenadiers or similar to build up a squad to whatever number.

Remember, I'm not talking about BOTs here, but REAL LIFE... It will almost certainly need changing for whatever game the bots are for.
