  A more subtle argument along these lines will claim that it is wrong to kill enemy combatants because enemy combatants are occasionally (or usually—depending on the strength of this particular claim) not responsible for their participation in war. This is especially true of conscript armies who are forced to fight. A pacifist might want to make an exception for killing soldiers who have malicious intent; but they may argue that it is immoral to kill soldiers who are forced to fight.
