Example:
_crate addWeaponItemsCargo ["arifle_MX_GL_ACO_F", ["muzzle_snds_H", "", ""], [["30Rnd_65x39_caseless_mag", 15, "arifle_MX_GL_ACO_F"], ["3Rnd_HE_Grenade_shell", 2, "GL_3GL_F"]]];
Adds a MX rifle with grenade launcher without optic or flashlight, but with a silencer. The weapon has a loaded magazine with 15 rounds left and and the grenade launcher has a GL grenade clip loaded with 2 grenades left. Note how "arifle_MX_GL_ACO_F" has an ACO optic by default, but it gets overwritten with "". The order of the attachments should be the same as in primaryWeaponItems ( [silencer, flashlight, optic] )
