Trained v qualifies. so simple.
Back in the late '80's there was a BIG push called Certification and Validation. Groups conducted Certifications -- a big skills lane, mission. PT test, Weapons qualification, 25 mi road march (we did that the night of a Lunar Eclipse -- had nothing better to do then watch it from start to finish. Oh, and sing 100 bottles of beer in the wall over and over
). It was pretty fun and challenging.
The idea was SOCOM wanted to have a say in Validating the readiness of the Teams it sent to the Unified Commands. Groups said they had to check the Teams first. In real life it meant if your ODA had not at least been Certified you were ineligible to leave Post. (didn't always work out that way, but should have.)
Great idea at the Group level, pretty hard to do at the SOCOM level. I bet the OpTempo today makes it impracticable.
