1. Shouldnt be in an infantery squad
2. Should be in a one man or 2 man squad if he wants a spotter (imo its best to do away with the spotter, with 2 snipers thats 2 less guns on the ground).
1. Support an attack.
The sniper can support an attacking team, by
- scouting out the flag before friendlies arrives
- Preparing the arrivel of friendlies by targeting high priority targets,
AA, if they land by air, TOW or HAT if armor is involved.
-while the attack is underway the top priority is again to take out high priority targets, such as .50 cal gunners, machine gunners, concealed infantery friendlies are not aware of.
-Deny the enemy cover

Everyone knows what happens during an attack, the enemy will go into cover, return fire from cover and medicate/patch up its wounded behind cover.
To counter that the sniper should set up on the opposite side of the advancing direction of friendlies troops. If friendlies move in from the NE the sniper should set up on the SW side of the camp, or at least displaced if there is no good spot avaiable on the SW side. That way he can take under fire wounded treated by medics, medics, and hostiles shooting from cover. Eventually the objective of taking out high priority targets is facilitated as well, seen as 50 cal gunners have some degree of cover if you face their front.
When the enemy lines are breached the sniper should move on to the next target while friendlies are taking the flag and repeat the cycle.
2. Support a defense.
The sniper can be a big help in a defense as well. He should
-report incoming hostiles. To do that he should set up himself far away from the general direction he expects incoming. If he expects the enemy to attack from the north he should set up himself 300 - 800 m to the north from the flag he intends to defend. He can warn his teammates about incoming troops and shoot attacking troops who believe themself into cover in the back, taking out medics and officers first.
If he cant set up himself in the direction of incoming enemies he should set up himself more or less along their frontline. If he thinks they will attack from the north he should set up to the west or east of the flag about at the height where he expects the enemy to go into position, shooting him from the side.
3. Search and destroy.
-depending on the map the sniper can move with a lot of reedom, especially on jungle maps. While it isnt advisable on desert maps, the sniper can be employed to search for enemy firebases and bunkers and take them out. He is less likely to be engaged and the commander does not have to dispatch a whole infantey unit for the job.
What he should not do.
1. Engage large groups of infantery.
The sniper shouldnt engage a pool of hostiles on his own just because they are there. People not being too scared to lose their virtual life will look for him and eventually find him.
2. He shouldnt operate within a squad. He needs to support the team, so he shouldnt just be long range fire for a squad.
3. He shouldnt do recon at the enemies main to keep track of incoming outgoing armor/troops. Imo thats something spec ops should do.
EDIT
4. He shouldnt engage when friendlies are in close combat with hostiles, there will probably be not that many targets for the sniper, since at that stage of the assault is a lot of movement.
At that stage he should move on to the next objective, if there are enough friendlies on the flag, the mopping up should go well and the flag be taken.
