Does anyone mob/guard bum for a living?

Something I’ve actually wondered about, is there or has there been anyone that’s basically not carried a civ job and just hopped on mobilizations and used that as their primary source of income? I know the Texas border mission is paying some good money and can be done voluntarily, as well as I’m sure other voluntary mobilizations, but it makes me curious as to if there’s soldiers that just do stuff like that for a living, or whether it’s feasible to do often enough to make a living. I’d imagine if you’re young and single, it wouldn’t take that much. Anyone know anything about this?

I’ll have a frosty and some fries, I just got back from lunch
