Gate guards wont heal me

[Vladolf Putler]

I am ally to united cities and I am constantly fighting near heft and other desert cities, I noticed that group of patrolling samurais will heal me if they spot me injured, but the gate guards wont do a thing even if I almost at the gate bleeding to death. If I hover with cursor over gate guards its green, they are allies, dont know what is wrong, I just want to count on them - I am doing hardcore dismemberment leveling so its intense and I need some external support from time to time, but I dont want anybody in my squad to join, not for now

The one thing you can rely on friendly guards for is a fight, they will back you up if they value your faction's relation over what your facing. If you wan't reliable heals then just self heal.
Town guards do (usually) heal prisoners when they aren't too busy.

As long as 1 arm is still usable it can be used to apply heals.
It would be wise to armor up the stomach & chest. The head if possible too.
Bleeding to death is less a threat with decent armor over the vitals.

Playing dead can be very helpful to avoid losing a fight too hard to recover.
1 easy method to playing dead is to have your unit (if still standing) remove 1 robotic leg.
This will cause them to fall over & play dead if in a dangerous situation.

Do not play dead near flesh eating animals.
It would also (even if you don't wan't to) be wise to keep a healer some where nearby.
They don't need to help fight so just keep them distant/hidden & on passive.
When you lose a fight have the healer of your squad come out of hiding & patch up.
