6. Can bots utilize the Commander mode? Can they lead or join a squad, follow squad orders?

Bots in Battlefield 2 can do all three of these things, actually. As a squad leader, they will generally keep their guys moving towards control points and respond to Commander orders. As a squad member they will follow their squad leader's prompts. Though, bots will not actually fill the Commander slot (so that the player always has easy access to this role) the AI will deploy artillery strikes, uav missions and supplies as requested by the player. The AI will also give Squad Leaders orders as if there was a Commander on the team and protect threatened control points with artillery strikes as well (or drop artillery on pesky campers, as needed).
