I have my sniper get close enough to the target so it gets in shooting range of the rifle and attack him. This mostly leads to two things: 1) enemy gets damage, combat doesn't start. I can kill him and other enemies who are around this way; 2) enemy gets damage, the combat starts and ends the same second so I can continue my shooting practice.
Sometimes enemies realize the trick and start approaching the party so I enter the normal combat, but this is rare. In other words I don't think this should work that way. It's a turn based game, no
