Player model glitches

I am having a problem in darkRP setting player models for jobs. THe character models move in a completely static manner floating along the ground instead of moving their limbs. Here is an example of the code which I use for classes in case it helps.

TEAM_TERROR = AddExtraTeam("Terrorist", {
	color = Color(75, 75, 75, 255),
	model = {"models/player/t_guerilla.mdl"},
	description = [[A Terrorist tries to fight against the state.  They can attack police, but they
					can't attack civilians.  The terrorists are currently at war with the mob and 
					terrorists may attack members of the mob as long as they do not harm civilians.
					You can raid solo or in a group.]],
	weapons = {},
	command = "terror",
	max = 8,
	salary = 45,
	admin = 0,
	vote = false,
	hasLicense = true,
	mayorCanSetSalary = false
