Plane: "Do you think the SEALS would be useing pistols or other wepons?"
As Sirs pointed out they'd have both sidearms and long guns, plus, plus, plus. One "plus" could be stun grenades. It looks like one guy might have been killed by that sort of thing in the pics CU4 put up.
SEALS are given a lot of latitude when it comes to their primary weapons. Some guys might prefer something in 7.62 vs 5.56 or 9mm. However, if the commander requests weapon integrity across the board then they have to carry the same primary weapon. Reasons for that kind of a request would vary from going in "clean", to everybody carrying the same ammo so that if you go down, for example, I can use your stuff. But whatever they carry they know how to use big time. These guys can really shoot.
