Stealth, deadly, the ultimate mission of you, behind enemy lines, is to cause forever troubles for your enemies.
1. What's behind enemy lines?
Generally, when you are not fighting in place your enemies expected to be, in particular, the territory which your enemies are supposed to be firmly secured.
2. How's it like?
While behind enemy lines, you are out of expectation of your enemies. Usually, when you really caused some annoyance to your enemies, like keep blowing up their tanks, vehicles, shooting their lone soldiers, there would be then some dedicated soldier(s) to hunt you down by all means, there would be infantries try to spot you and mow you down, tanks to try to drive you out of the bushes with their HE shells, or worse, planes to strafe and bomb you to pieces.
It's easy to see, unless you are acting really tricky and skillful, you would mostly get killed before causing enough damage to compensate the effort to get behind the lines.
3. What you need
Typically, people carry rifles, AT weapons, landmines, smoke grenades, explosives on such missions.
Obviously, you would be outnumbered most of the time and thus direct confrontation would be the most stupid method, short-ranged weapons like SMGs should be mostly avoided unless you have no choice. Rifles are best since they could kill by one shot and thus lower you chance of getting detected (obviously, it's more easy to locate you if they hear continuous bursts)
You would certainly like to destroy those damn armour that keeps rolling to the front and kills you teammates. You have enormous advantage of back there, first, people would be less alert while driving in somewhere which is supposed to be secured, making it easier to surprise those tankers, also, tanks driving out of main bases are mostly unsupported by infantry and makes them easier prey.
In africa, landmines are you friend, even laying them on the road would leave a few burning wrecks there. Of course, a hint would be not to lay all 3 mines you have, reserve one for special purpose.
Mines are especially useful when you try to shift you location, it effectively seals the route your enemies would use to hunt you down, nothing more rewarding than a guy that think he had got you to be blown to pieces.
Binoculars, a magical tool that not only magnifies the battlefield, but also could tell effectively where the enemy is. In addition to that some dedicated gunners are ready to put shells on the ass of tanks/AT guns that are camping your teammates to death. Only one thing to remind is that, your player model speaks when you spot/report enemy positions, you would certainly like to avoid that when you are close to a bunch of enemies.
At last, smoke, yup, smoke grenades, are magical stuffs to confuse your enemies, as people naturally would like to figure out what the hell is in the smoke. Your enemies would start running randomly like the smoke particles if they are engulfed by smoke, perfect chance to shoot them.
4. Stealth
There are some important points to bear in mind to maintain stealth
a. Fire to kill
The first principle of maintaining stealth, if you can't kill, the noise of your gun quickly expose your position
b. Radio/chat silence
No voice commands, no grenades, no smoke grenades unless needed/unauditable to enemies.
c. Don't run in the open
Even an idiot could spot people running in the open easily, if necessary, even try to crawl up.
d. Shifting your position
Soon people would start throwing nades into suspected places, or worse, artillery landing on you, better not risk that.
e. No engines!
I am pretty sure that stealth is impossible with engine on, also, minimaps would betray you and give away your position when you bail.
5. The fox's way
a. Irregular attacks
don't keep shooting your enemies in the same place, I mean, don't let your enemies to keep dying in the same place. Let them survive, this could make an impression that you have left the area. Sometimes it also makes your enemy extremely nervous and waste their battlefield resources on trying to spot you.
b. decoy mines
S mines could be a good way to deceive your enemies of which direction you are at, other than placing them near you, place one away from you.
c. patience
it's sometimes not a good idea to attack targets that's tough to deal with, such as a blob of infantries.
d. decoy squadmembers
to let your squad leader to shift postion or escape(if you have any...), a good idea is to have squad members to attract firepower somewhere away from the escape path.
e. use enemy stuffs
get ammo from enemy APCs, get stuffs from people you shot or even use their MG / AT guns when needed.
