The SPAS 12 (commonly designated as the Shotgun, for there is no other ones in the game) is a Primary Weapon the Support Unit Class have. Like a regular Shotgun (in reality and in other games), its attack spreads apart more and more as it reaches a further target, making it hard to attack further range targets. However, the Shotgun is very powerful, so powerful it can kill any light armored unit in one shot, medium and heavy armored units in two, but only if the shots are were placed . Sadly, along with its inaccuracy, the Shotgun also has a high Cooldown, one shot only every 1.4 seconds. But if you can shoot accurately, it is lethal to recons and other light amour units.
