Hit registration does not compensate for latency. Players must shoot at the position where the enemy will be in a time equivalent to their ping. For example, a player with 200ms ping will need to fire at the position where the enemy will be in 200ms (for a running soldier, this is a couple of steps ahead). If the player shoots directly at the enemy, they will observe impacts, but the enemy will not be injured. Faster moving objects, like vehicles, are more problematic. As an Australian gamer, this affects me significantly.
