why du some special forces use submachine guns or standard assault rifles durin certain ops, wads the reason. is it bcoz of close combat battle or wad...
It's because of the type of operation that they are in.
wad kind of operations and why?
assault rifles can often penetrate thru objects. Which is desireable sometimes when u dun wan the enemy to have a place to hide.
When it comes to hostages, u might hit a hostage accidentally if the bullet flies thru the enemy's body. Thats when subsonic, but hard hitting rounds like 9mm is prefered.
Choice of weapon also depends on space, how much room to move around. If its tight, u dun wanna fumble around with an m-16 rite?
if the enemy have body armor, u need a armor piercing weapon like a rifle, but becos its tight, u cant have a rifle, how? Opt for BULLPUP rifles, or short rifles eg, M4, or High penetration SMGs such as the P90.
