I have a problem where NCR troopers I summon with the NCR Emergency Radio will automatically run away from any combat. The first time it happened I was clearing out deathclaws and decided to attribute it to abnormally good AI, but during my most recent playthrough it happened going up against the Legion at Cottonwood and against fire geckos as well. Is this a bug/glitch or are NCR Troopers meant to run away from anything tougher than radroaches?

As a side note, NCR rangers summoned with the radio don't have this problem.
