The Rebel Ambush was a unique promotional power that could be selected by GLA generals of a certain rank. This ability enabled them to place a small group of Rebels anywhere on the battlefield, seemingly as if from thin air. Quite how these Rebels managed to 'appear' in such a way is a mystery; presumably they were trained in stealth, or similar. Whatever the case there were 3 ranks of Rebel Ambush; at its lowest level only 4 Rebels would appear, progressing to 8 and then 16 Rebels.
