Dealing with larger groups

[Devonian]

I would probably either wait for them to move or, move on myself if it looked like they staying and would be a problem for me.

However, if I "had" (for whatever reason) to start looking at attacking them, then I would do it in the dead of night; look at sabotaging equipment/vehicles; stealing supplies; and then causing chaos, confusion and fear - petrol bombs/flaming arrows etc. Ideally I'd want to see fires being set off in multiple locations at the same time, and then just slip away into the darkness, making sure I moved a considerable distance from their camp, as when morning comes they will either be hunting you, or hopefully moving on quickly........

If they are hunting you down, then lying low and picking them off one at a time, would be your only option, but then how large is a 'large group'? If you are talking 50+ then the odds really would be stacked against you and the best thing to do would be to get moving in the opposite direction.
