Player falling down into prone position instead of playing animation

[Tochka-U 0]

so i want to make a small brief session where the players are in a static c-130 (the cup object) and can only move their head (il appreciate if you can help me with that as well) and when they are in an animation but when i start the mission the player just falls into prone position instead of actually playing the animation ive tried to change the "switchmove" command to "playmove"/"playmovenow" (idk if that even should work) so anyway please help
