I think the last time some invasion or war within the US qualified for haz-duty...June 1942...Aleutian Islands of Alaska. Maybe some history PhD guy can correct. I don’t think Hawaii counted (until after FDR declared war and they’d left the region).

New Mexico National Guardsme - 200th Coast Artillery battalion were deployed to the Philippines on September 1941. They ended up in the Bataan Death march.

Well we now have cartel gun nests on top of the mountains in Southern Arizona, they have operational military control of most of the border now, and the Mexican "army" is really just another more powerful "cartel" (=mafia).

If that don't qualify as a "war zone", I dunno what would. They certainly think they're conducting a war against the US...
