Here are ways to glitch on th - SOCOM: U.S. Navy SEALs
Here are ways to glitch on the online system.
The ladder glitch:First you climb all the way up the ladder.
Then you ladder slide down. Then turn arouund slowly and you will see the climb button press X and then ladder slide and your in the glitch.
In most ledges that you climb up you can run straight into them with your handgun out and you will get in the glitch.
Night Stalker: This also works on a couple other maps.If you are a terrorist then go up the stairs close to where you start out. Keep going until you see the hut.
Then jmp down and look at the ledge climb up on the left side of the ledge and that will get you in the glitch.
(This also works if your a seal buts its easier to get there as a terrorist).
