Guerilla also has some nice advantages. If you place a guerilla squad or 2 on one side of your deployment zone, your enemy MUST react to that, or else your guerillas are going to march up that side of the board uncontested. But, if they do that, they risk you moving them to the other side of the board, leaving those squads well out of position, and scrambling to get back into a useable position. I won a game because of that, backing up the guerillas with a couple of great greys. redeployed the guerillas, and moved the greys to the other side (move 6 really helps with this). Had all troops basically charge up one side of the board, while 1/2 of his forces were on the other side of the board, effectively useless.
