I know they specifically mentioned temperament in the selection section of one of the sniper manuals. Not sure about special operations.

Honestly, most special operations selection processes seem to have very little to do with the actual what most Tier 1 units actually do. CAG, for example, has a 40 mile solo nav course as part of their selection.

Yeah, they are sort of just the worst in JSOC (although one wonders about the CIA direct action groups). But between this shit, the Nazis in the KSK, and Australian helicopter musical-chairs, it really does seem like there’s something about special operations that attracts the worst a country has to offer.

In their defense, it turns out that a lot of the insanity and violent mood swings are related to brain damage from firing 10.3s indoors constantly.

But on the other hand what the fuck.
