Ok I'm gonna need help with the assaults. Your mauser #1 just fired at my #1SMLE and you rolled. What should be my response? I will also check the manual you provided.
Since we have LOS to each other, we were able to attack, you can either return fire however you want or move out of LOS before the FACE DOWN disrupted becomes FACE UP & the effects of it are in play for that unit. It DOES NOT suffer -1 to attack or defense until it becomes FACE UP. Also, once it does become a FACE UP disrupted, you cannot move that unit until the disruption comes off in the Casualty Phase of the NEXT turn.
Were it me...I'd return fire..remember..training game & this is part of learning the game...or you can do as I posted above or any other legal allowed action
You could move 2 or all 3 units to the objective hex & make no attacks with those units at all this & move the Lt. & Vickers into the hex now occupied by the SMLEs & not be attacked at all...I have already done my part of the Assault Phase, so I cannot make any more attacks this turn.
