Tatics are when you supress your enemy and flank his position and destroy him. Hiding behind women and children and spraying rounds over their heads not so much. It is more like they are scared that our troops are better trained and disiplined with sound tatics. So when you are out gunned and out manned and out classed you resort to tatics of cowards. Most people would crap their pants if they faced a Abrams tank or a gun truck with some of Americas finest and bravest. Can not blame them for resorting to what they do, but if it walks like a duck and quacks like a duck.
They are simply "Taking effective cover". But your missing the point, it is a classic Guerrilla Warfare concept, and you would do the same thing (sort of ), They KNOW they are lightly armed, poorly trained, with spotty leadership, so they do not attack an Armored Brigade with an overloaded taxi .instead they attack WEAKNESS.
It's pretty basic common sense, The evil capitalist infidels don't shoot at women and kids, They don't use their most excellent Counter Battery fire on Hospitals or Mosques, Gee, maybe I should take the stuff I don't want blown up, (My weapons, my Ammo supplies, and my butt ) and spread it amongst Mosques, Hospitals, Schools, and other places the ROE say they can not shoot at.
