The demonstrated incompetence and poor to nonexistant equipment of Federation security and infantry forces should ba a real help to our insurgents, at least at first. Modern-day miliraty forces would slaughter Starfleet Security.

I wonder if a replicator could make a decent assault weapon and ammunition for it? I don't see why it would be impossible, it's just metal in not terribly intricate shapes. It might be nessecary to replicate the individual parts and then hand-assemble it. The bigger problem will be developing the replicator patterns. Our insurgents will may try and find an antique weapons collector with working weapons to reverse-engineer. Rediscovering proper military gear could be a major plot arc midway through the series.
