Unit - Flee

[QueloR]

This is probably a silly question... But I cant find it and Im tired of looking.
How do I make my unit stop auto run when hit?

EDIT:: Jesus... Figured it out.

Every (or pretty close to all) units have a command called hold position its hot key is H. What this does is stops units from moving no matter what but if something comes close enough they will still attack it but they will never flee when attacked or chase after units when they get attacked or enemies get close.
