For a fine example of superior performance under extraordinary stress, check out FAUDA on Netflix. It fictionalizes the operations of the mistavrim, the deep cover counter-terror units of the Israeli Defense Force. Similar to the “pseudo ops” of the SAS in Malaya, or the Selous Scouts in Rhodesia, the mistavrim mount long-term deep cover operations that subject their operators to unimaginable levels of stress for weeks, months, and years at a time.
FAUDA is written, directed, and acted by veterans of that unit.
They are extraordinary performers.
