I'm not quite sure if I understand what you're asking of, but I'll try my best to clarify:
Answer 1: there are two actions that allow a model to make a number of melee attacks equal to its A value -
strike and
counter-strike. It means that when you perform one of those actions you swing your weapon the number of times equal to your A. "A" stat doesn't determine the number of strikes or counter-strikes.
Model may perform the strike action during its
operation and counter-strike in the enemy's operation. So one strike and one counter-strike per game turn.
EXAMPLE: let's say you have A=3
- if during your operation you find yourself engaging an enemy (in base to base contact with him), you must attack him three times (make three
hit rolls). In case you engage more models, you may divide those three attacks amongst them, but you always have to make all your attacks, or withdraw. You cannot do nothing while engaged.
- counter-strike action is always made as a response to enemy's strike. So if anyone attacks you during his strike action, you counter-strike (again make 3 attacks, but only against the attacking enemies). Normally there is only one counter-strike allowed per
game turn and must be made against the first enemy (unit) that attacks you.
Answer 2:I think the most important side effect of "receiving wounds" is death

In Warcanto language every time an enemy makes a successful
damage roll against you, you receive the
blood token. If you "collect" the number of blood tokens equal to your L value - boom! your dead (
incapacitated). If you have L=3 and you receive one (or two) blood tokens you're just close (or very close) to your doom, nothing more.
Good Luck on monday!
