Recommendation weapons in BF3

Today we are going to find out which weapon that can suits you well in the battlefield 3.

For MP7, I love to use it. I think that this gun has 41 ammo per chip and the damage that MP7 can make is a lot. Sometime, I can kill three enemies in a round with that. I think that you should use support for this gun because the high rate of fire. The ammo will run out so easy and only support can have unlimited ammo. My highest kill stock is 56 and I use MP7 to achieve that. I think that this gun is really good to use as the close combat but it also has good damage for long ranger.

For this grenade launcher, it is really good to use in the subway map. M320 is good for killing the enemies from distance and from a difficult place. Using this weapon is really easy because for the most of time you don't even need to aim for the enemy. 

Here is my battle log. I think that you guys can see what guns that I prefer to use.
