Their use is tricky. The most common types are immobile emplacements used for anti-air defenses and man portable bazooka type units. The ones used for anti-air defenses are best suited for deployment on hills that cover large areas within the SAM's line of sight, and the man potable one's are best used in attacks of opportunity, since their small unit size makes them hard to spot where they can lie in wait, though, they're easy kills so it's probably best to keep them off the front line. Take advantage of their small size, keeping them out of sight, waiting for attacks of opportunity. There are also SAM's that are mounted on vehicles. These are a different story, as they are easy to spot, but they can move great distances quickly and kill enemy vehicles more efficiently than the man portable one's, but enemy tanks can kill them easily, especially if their mounted on soft vehicles, so be careful.
