It has been widely reported that the operators that killed Bin-Laden were using "Silenced" suppressed weapons. Then I heard that part of the reasoning behind not releasing the photos, was that the "high powered rifles" used by the soldiers left a "devastateing wound". OK, I know enough about suppressors, to know that you can suppress the muzzle blast of about any rifle, but any projectile that is super-sonic is going to have the loud crack sound we associate with rifles. I know these guys use suppressed MP5's for hostage rescue stuff, but I can't see them carrying these on this raid. How loud are suppressed M4's? I've heard about a sub-sonic sniper rifle, a company not far from me (SSK) makes some. It's a .30 cal bullett in a smaller case. Please enlighten me. What do you guys think they were using?
