Stargazer Units, make them harder to kill and add special zones

I think they need to be reduced in numbers.
They need to be have an awake phase which makes them check their surroundings slowly.
Allow them to tumble away from enemies when they spot you.
Then give them unique hitzones.

Current hitzones:
There is always a headshot for those units who are wearing the shortsleeves.
There is usually upper chest shots for the ones wearing the balastics masks. Heat shots take a little too long because the helmet usually is broken first which then can be finished off with a headshot.
The Heavy Gaurds are always double headshots as their armour is way tough to shoot at.

New Hitzones Ideas:
Add a hitzone for knee caps, which should totally throw them into states of pain in which they can’t fire.

Add a hitzone for weapons (to shoot it out of their hand) so they either have a backup handgun which is slower or they must run to their nearest dead body and pick one up.

I see them as sheep right now. They must get more complex.

Thank you for reading, that is all.
