Advanced positioning and tactics pt.5

Breaking the Walls of the Fortress
Sometimes, the opposing team has organized themselves a prime set-up; you're simply "pinned down" and there's nothing you can do about it right now. The first thing to do is duck and cover, and make sure your team mates do so. Don't give the enemy free kills.

Once you've organized yourself defensively, you have two options:

Wait for the opposing team to reposition themselves "which is the point of which their formation is weakest." Sooner or later, they'll tire of their positions and simply decide to cover other possible openings.
Attack in such a way that forces them to reposition to locations where they are weak. Throwing grenades will accomplish this; firing off Battle Rifle rounds may also force an opponent who was covering you into hiding, giving you an avenue to move up.
While your opponents reposition themselves, push in (not too fast or your team will all die at the same time). Naturally, do your best to avoid a forced repositioning when you have the advantage.

Checkmate
In team games, and even FFA games, one of the worst situations to be in is to be in a fight where two people have the advantage against, and over you. Think about everyone, or at least your target's position and consider possible locations where you can kill him/her in a double "team" situation. Time your movement and read your opponent's path. And determine whether anything can draw your target's fire away from you. This way, you can reduce the amount of damage you can possibly get, and at the same time maximize the amount of damage your opponent will receive. Your target's only option is death, if you do this well enough.
