i been playing socom 2 for a good long while to develop these nice little strategies for the seals breach. these COAs should be effective to getting the job done or trick the fools.
Sujo
NOTE: the way I see it, breaching the center on this map will make you more vulunable to the terrorist, they will circle around you much faster. so unless you got these boys owned(i dont mean seal won the round, just down to 1 or 2 guys), dont breach the center.
Wave 1: Alley Race
This tatic requires distractions. have the seals team(of all

split into 4s. now one side runs up to the left side breach while the other races through both breaches on the right side straight to the bomb room after the left team gives the OK to advance all the way. now the team on the left should have one guy sniping by the billboard for bums stationed on the turrets while the other guys make some noise on the left side. that way, the guys on the right side can head out when the sniper gives the green light after taking out the turrets and terrorist snipers. the terrorist will most likely think they are all advancing from the left and focus most of thier firepower on the left side. right side team runs in, plant the bomb and kill any other tangos.
Wave 2: Fear the Stealth
This one requires intimidating taunts, if the terrorist bastards like to launch off grenades after grenades, that is a big problem when trying to breach the walls. if theres 5 mins on the map, have everyone hide around the start point and wait 2 mins, 3-4 mins if theres 10 mins on the map. once the time is up, advance slowly while throwing out taunts like "look behind you" and "are you blind, i right here", those kind of taunts to scare them good. if the map has the 5 min limit, have everyone race down the left side, climbing up that ladder the airstrike 'foxtrot' "missed", and run straight into the building. good, now they might still think your all still out on the field or they are hot on your trial if they caught you on the roofs. make sure everyone is in while still throwin out taunts, watch the mines or they know where exactly you are, plant the bomb and take them all out.
Wave 3: Misguidance
if the enemy your fighting is smart, then they know all about the sound thing, otherwise this one might be too easy against an idiot. choose the left or right side, breach a wall, then hide in the trench near the center breach. if everyone cant fit, have them hide on the roofs nearby. unless these are grenade throwing lunitics, they will race to which wall has been breach if they follow the sound right.then have everyone emarge and ambush the bastard. this tatic might not be fully effective, especially for the first and second round, so use it as a last resort.
Enowapi
NOTE: the tougher the terrorist, the trickier this map can be for you. there are also two spawn points, the one in the water i call the north spawn, and the one near the front breach wall i call the south spawn.
Wave 1: Front to Back
those in the north spawn point should be the ones to get the bomb and those in the south spawn point should do this; turn right and race up the cliffside towards that MGL tower.
becareful here; they like to either sit in that grass and wait for you, plant mines in the area, or have a sniper sit across in the base looking at the MGL, or all three. if you see a guy sitting in the bush, shoot him and toss grenades. as for the possible sniper, dont climb the MGL or cross the bridge, he'll take you out like that! hide where you can see him but he cant catch you yet and with a good range weapon (preferbaly the M4A1 SD) gun him down ASAP, then man the MGL.
now about the north spawn boys, call airstrike echo and breach the front door. dont storm in, they might have a trap to slaughter you. instead, run up that zigzag and wait there. south spawn boys, whoever is on the MGL should bombard the place crazy but carefully, not near the zigzag. if the terrorist aint all that tough, they should be underground now. north spawn boys should now race in and around the base for anything that survived after the MGL man stopped. south spawn boys, race across the brigde, and watch out for mines, breach the wall if you want, then head toward the ladder in the back and throw a grenade down there just incase. north breach boys head towards the ramp in the front and throw a grenade just incase. both sides go underground, kill, plant, and get out.
Wave 2: United Death
are these terrorist being a pain in the *** with the grenades? the north and south spawn points should both meet up at the MGL. if picking up the bomb is gonna be near impossible, than planting it is out of the question, you just might have to elliminate them. at the MGL, look out for jumpers in the bushes and snipers across the MGL. if you can get the bomb, call echo too then race up the zigzag. meanwhile, breach the back door and kill whatever you see. if someone else is still alive but aint in the base, hurry and plant the bomb if you got it. otherwise, hunt him down.
Wave 3: Sidewinder
have everyone hide somewhere, wait a short while then call echo. then wait a little while longer. ready? race up that front breach, blow the door, storm in and plant the bomb. if they are stupid enough, they would of been expecting you at the side breach.
SandStorm
Wave 1: Backside Rush.
now what you wanna do is have everyone storm in from the right side breach as soon as the round start. they might call in the airstrikes but 9 out of 10 times, on the plains. but should the cliff come under attack, make sure everyone is behind a big rock. once you breach, you gotta move fast. dont go on the high road at the first fork or down into the training area, stay low on the center path and head to the next fork, this time stay to the extreme right, while double checking for snipers along the way. is everyone with you? good, now you should all be at the back of the terrorist camp. now split the whole squad into two teams of 4. one will take the bomb straight to the target area, via the stairs while the other gaurds the two doors and takes out anyone who approach them.
Wave 2: Center Rush
the name says it all. basically, you and everyone just gotta race down to the center breach and plant that bomb ASAP. you wanna wait a few rounds before doing this trick so you catch them briefly off gaurd.
