Hello there! i am finding all these good spots to kill people and i have come across a great spot. Okay this is what you do.
1. go to the map part where there's a hole in the ground with the cap thing and it has two ladders.
2. climb up the ladder that faces the hill slowly until u can see up the hill.
3.Have fun killing the people that are guarding the flag.
Advantage: if you use the l9 sniper rifle then you can 1 shot kill everyone that is running up and the hill.
Warning: you can not see the bravo behind u trying to get to the alpha flag so watch out
