A question about NVA Attack op, if you have both Troops AND Guerillas in a space ...
It seems the NVA Attack operation only allows you to attack with Troops OR Guerillas but NOT BOTH.
Correct for a single space.
You may Attack with Troops in some spaces and with Guerrillas in other spaces during a single Attack Operation, however.
Adding the Ambush special activity doesn't help as it seems to just change the Guerilla attack procedure, but only if you are doing that in the first place. Right?
Correct if the Guerrillas are located in the same space as the Troops.
However, Guerrillas on a LoC that is adjacent to a space with Troops may Ambush on that LoC in order to remove enemy pieces from the Troops' space, thereby combining the effects of the Ambush with those of the Troops' Attack.
