yes, HOD, but a co-worker and I play "PB3", a variant using my in-house rules. Main changes are:
1. A unit has to spend its move to go into "overwatch." So you either move, or you stay put and are eligible to fire opportunity/overwatch fire (tanks can move half and still overwatch).
2. Units are grouped in "formations," usually battalions, and draw a chit for that battalion. This way you don't need any "spent" markers which drive me crazy. When your battalion's chit is drawn, you just move that unit (it still has a command range...this keeps the unit together).
3. When a platoon is destroyed, the battalion's ability to rally is reduced by one (introduces loss of morale and fatigue).
4. AFVs have facing as they move, into the hex they move into, so that opportunity fire against their flanks has a -2 advantage.
Creates a much more realistic feel to the game, we feel.
