How to script a unit to never lie down or crouch?

[Rigel 10]

Suppose you want to place a sniper in a building. You want him to stay still, shooting whichever target he sees out the window. But the AI has this habit of lying flat on the ground when its being spooked or shot at

so how do you tell the sniper to ALWAYS stay still and to never crouch or lie down or move around aimlessly? :j:

mySniper setunitpos "up" => this will keep the unit standing

mySniper disableAI "move" => this will keep it from moving
