1. Put down a unit as a player in the editor
2. Add this to the init.sqf

[] spawn {
	removeAllWeapons player;
	removeAllAssignedItems player;
	player setUnconscious true;
	uiSleep 3.0;
	player setUnconscious false;
};

The player will now be stuck in an animation where they can not get up. One workaround is to use player switchMove ""; but this results in an erratic and horrendously ugly animation.

The best workaround I have found thus far is to give the player a weapon just before you disable the unconscious state and then remove it. For example;

[] spawn {
	removeAllWeapons player;
	removeAllAssignedItems player;
	player setUnconscious true;
	uiSleep 3.0;
	player addWeapon "arifle_MXC_F";
	player setUnconscious false;
	uiSleep 0.1;
	player removeWeapon "arifle_MXC_F";
};

The player will now play the proper animation to stand back up even whilst unarmed.
