Spawn with a random gun (has up to six attachments), switching weapons will always provide a new gun. When selected, this will replace both the player's weapon slots in Create-A-Class and will remove the Cavalry Shield.
Any weapon can be obtained (includes Melee Weapons and Launchers), even if the player has not unlocked it. Each weapon spawns with two magazines, one already loaded and one in reserve, with the exception of LMGs, which only spawn with one magazine loaded (as a balancing factor to force players to switch weapons). Incendiary Rounds for shotguns will grant the full amount.
Melee weapons can be kept for as long as the player wants. As stated in the basic training's description, any attachment may be equipped, although the last few attachments such as the Tactical Knife and Suppressor seem to be more common. Akimbo for handguns is somewhat rare, and does not appear with other attachments.
