Yes, the higher your rank, the more troops you can have follow you at once using the "follow me" command, I believe the numbers are:
Private: 1 guy
Sergent: 2 guys
Captain: 3 guys
and General: 4 guys
Having a couple of bots following you around can really increase your chances of success. It's fairly useful I would say, if you make the most of it and take the time to get yourself a squad, instead of just running headfirst into combat and getting gunned down. Somthing I really need to learn to do.
Not being paranoid doesn't mean someone isn't trying to kill you... or does it?
