Hi, I just got this game and I'm finding it hard to hit enemies on the Sniper and Convoy mission with the MK12 rifle. I have a legitimate copy, so I don't think this is FADE, unless FADE can sometimes be activated erroneously. I know I have to aim slightly above targets at long distances, but sometimes it seems like I've hit the enemy (no dust puff appears near the ground) but they don't take damage. Is this because of their armour? How many shots should it take to kill them, and do enemies show a reaction when hit in their armour?

Hello there,
First of all i would like to say that there is no armour on infantry targets, they always get hit, the only thing that mught be seen as armour is that sometimes you might to have to shoot them multiple times.

There are two reasons why you could be missing them.
1) Distance: What distance are you shooting from? Shooting from 300 meters: just aim dead on. If you are shooting from further away you might have to aim up more.
2) Leading: Are the targets moving? If the targets are moving you need to fire in front of them because it takes time for the bullet to get to it's destination. The bullet is not instantly there. Again if you are firing from far away you have to compensate more for this effect.
