popular science, like 4 years ago...
they had a 4 pager on Seal equipment; their guns, the "raft", night vision, etc
well, they had breakdown of guns (jus like rogue spear), MP5, shotgun, etc etc and sniper gun
well, it was quoted from a SEAL instructor about the .50 caliber sniper gun, said had a whistling noise...
true, it goes faster than speed of sound, but hey, that is wat the instructor said...
again, he said "u know when ur getting shot by this sniper gun"
well, i jus remember that article well enuf to kinda recite it back after 4-5 yrs
