Two guys with apparently only 1 handgun between them against 5-6 guys with Xiuhcoatls (cheap Mexican copies of the G36). There's a term for guys like them; Alive.
The ridiculous one (who if anyone should be court-martialed) is whatever idiot sent them there without a full loadout of rifles, pistols, body armor and helmets.
Mexican troops on American soil should be assumed to be cartel and shot on sight.
