Two Russian MMCs (4-4-7s no special SSRs for AT capabilities), one concealed and one not concealed both pass PAATCs from separate hexes and enter the hex of an in motion BU German PzIVH (3/5 MGs). Please help guide me through the proper sequence of play (i.e., Ambush, attacks by the MMCs, attacks back by the AFV). Does Ambush only occur if the AFV is in a woods/building hex (or using bypass) or if being attack via Street Fighting? Thanks in advance.
