Not that I know anything about it, but...
My guess is that the CO is a petty tyrant, that is using his forces to sweep and scavenge everything locally. That's where the "weekly supplies" are coming from. Also would explain all of the dead bodies - we're assuming that the "ones with guns" were shooting at Zombies. Not necessarily.
First step is to eliminate all the people who might be inordinate drains on resources - medicine especially. "I'm a doctor and I'm here to help!! Show me who's hurt!". Yeah, right. Also might be that there's not much for medical supplies. When Mom stops getting help.... people who love her start getting agitated. Which leads me to step #2...
Second step will be to eliminate the malcontents (we're not there yet).
Final step will be to cut and run once the zombies show up, or all of the local resources are drained. Wouldn't surprise me to see everyone wake up one morning and have the "safe zone" completely devoid of troops. "Where did everyone go? What's happening? etc.
FWIW, Rick, Glenn, Carol, etc would steamroll the people in the "safe zone". Troops and all. Would be like Godzilla vs Bambi.

One needs to remember “the Walking Dead” refer to those still living. So your points may have some merit. But they did remove the malcontent fat neighbor with the bad ass convertible Malibu and the CO (who need to be fragged but I see him eventually being eaten alive) even stated that fact.
