a. this is israel
b.the guns are M16, only a few units are using the tavor, these units don’t include such amounts of girls, and they don’t have time to take pictures in the shower
c.the girls are in basic training which means they have to carry the gun wherever they go, which included sleeping with the gun under the mattress instead of a pillow or it will be stolen by the commanders at night.
c. since girls basic training is a formality the guns are generally in a very bad shape as it is, i mean they can fire but the bullets get stuck often and there is a real chance that in battle the thing will be pretty much useless
d. actual bullets are given when you are released home on the weekend and when you are learning how to shoot, most of the time, while running around at the base, they are pretty useless.
e. just so you know it’s pretty heavy and annoying to carry around the thing all day
f. just so you know #2: most girls come up with a funny name for their gun in the beginning of basic training, I remember calling mine fluffy

live long and prosper

And to answer someone else, they are M16A1s. You can tell by the lack of elevation-adjustable rear-sights.
