To use the sf14 script (load/unload the Sf14) add the following to the init script of the Sf14: this exec "sf14.sqs". After this, when the hetzer/bergehetzer, wwIIec hetzer, wwIIec stug drives next to the Sf14, it can be loaded inside the vehicle from the action menu (It takes a while for the game engine to 'realise' the presence of the new action in the menu). When unloading the SF14 from a vehicle, it gets unloaded right behind the vehicle it was in, facing the opposite direction.
