I have recently found that shot in the head hurts so I would suggest you get a helmet. They cost $20. They come in green or black.
Tactical  lights are also we also helpful. They go well with a pistol. There are several youtube videos that use lights. Make sure they are high powered.
Grips are another thing. The strait collapsible grips are good for close combat. The triangle grips are my favorite. The are good for close combat and don"t get in the way when fighting.

how to break the L shaped assult

The L shaped assault is the most common assault. You break it by sending (Lets pretend there is a red, blue, and yellow squad) the red squad to assault the L its self. Blue flanks the short part of the L and yellow flanks the long part of the L. Hopefully you have few casualties.

 

The Good, The Bad and The ugly

The Good: This summer I recently went to an airsoft Ranger camp. It was awesome learned battle tactics and how to ambush enemy. I was named, the next day, the best ranger on our 42 man platoon and made leader of the platoon.
The Bad: Half of the kids there did not know the rules at the camp. Some of them don't know hit meant, after they did that to me they found out. Kids also keep throwing smoke grenades at me. That was not fun.

The Ugly: We lost (except 3 missions) missions and they weren't because of my teachings the kids didn't want to get hit.
