Fog of War - S3-E13
Stupidity: The team is trying to figure out how Dr. Craig died during the rescue attempt. They don't know if it was a suicide vest since in another part of the structure Clay neutralized an enemy combatant wearing one. They need to figure this out before they land to satisfy command. They recovered his body, they have highly trained medics borderline trauma doctors on the airplane, could they not examine the doctors body to see if he has shrapnel, burns, bullet wounds for clues?

Siege Protocol: Part 2 - S3-E12
Stupidity: This team never packs enough ammo. The two little skirmishes they were in maybe consumed 120 rounds each x8 guys makes 1060 and that's pushing it. A soldier's combat load is 7 magazines, 210 rounds each for their primary weapon system. These dudes should have at least 3 mags each left, and Seals being Seals fighting far from the main force always pack more ammo, at least 390 rounds. There's a Seal training video where Seals are doing a centre peel drill and it says they pack 4000 rounds for 8 men. (00:49:15)
Siege Protocol: Part 1 - S3-E11
Stupidity: The team is going on a CQB raid to free some hostages; so close quarters battle, room clearing, a very high chance of getting shot since the enemy can hide anywhere. They are not wearing plate carriers and their armor. This is the very mission that military doctrine emphasizes armor. It's not a long range patrol through mountains where weight matters. However on a previous mission to locate a downed pilot in open terrain they were wearing plate carriers. (00:27:12 - 00:28:00)
Answer: They should be wearing balaclavas. They do such operations usually on foreign soil.
