Realistically the 1 vs 100 camp thing has the issue that the 1 has to get lucky a lot*, the 100 only have to get lucky once (even if the level of luck for both are unequal)

The problem the 1 has is the moment the alarm is raised and a significant number get roused from sleep they're done unless they have a very good escape plan.


There's also the point that in a lot of TL's a military camp of 100 will likely include some manner of watch animals


The sniper at least has the advantage of range and position making getting way once their actions are discovered is easier (but here we get into the fact that suppressors aren't that good and sniping at TL6 at night is not going to be that long range) especially if the camp being shot into is relatively quite. There's also the question that it's unlikely that this sniper is going to find a position they can shoot all 100 potential targets from without relocating several times (and of there is one why doesn't this camp have sentry team on it!)



*Unlike in films and computer games if a sentry spots or hears something odd they tend to alert someone else first before investigating rather than going to investigate without telling anyone and then being conveniently silenced.
