My opinion would be 1 or 2 sidearms each with a minimum of 100 rounds total, 200 better. A rifle like an SKS is not out of the question, you can still get them everywhere. The rifle ammo should be 50-100. A tactical/combat knife and flashlights for each person. Urban assault gear is a plus like web vests, masks, jackboots
Rope is good. The idea is to travel light, yet be prepared as much as you can without getting weighted down. The ammo will be the heaviest burden I think. That would be a legal setup. For the lawless merc you would need only modify the trigger group on the SKS for full auto, and that would be one major difference. Just my .02 for fun.
