The command addWeaponItem includes a parameter to instantly load the magazine, if the item being added is a magazine, without an animation or reload time. However, this command only works on infantry units, and no equivalent way to force an instant reload exists for vehicles. This can be inconvenient when trying to script certain weapons with long reload times, such as artillery.

Proposal: a new optional parameter for addMagazineTurret that works the same as the addWeaponItem parameter. If it's not possible to modify addMagazineTurret in this way, then a new command such as addMagazineTurretInstant that does the thing. Alternatively, this could be added to loadMagazine.

Examples:

_veh addMagazineTurret ["gm_30Rnd_105x617mm_apfsds_t_dm33",[0],30,true];

_veh addMagazineTurretInstant ["gm_30Rnd_105x617mm_apfsds_t_dm33",[0]];

_veh loadMagazine [[0],"gm_105mm_l7a3","gm_30Rnd_105x617mm_apfsds_t_dm33",true];
