I presumed a Sgt would be leading the guys? What I understood, listening to the verbal, the main man was in a vehicle behind the boys, shouting out orders to them. Is this the norm?
Why would you presume....
The Sgt did this run 12/15 years ago and has nothing to prove. They are there to oversee the training exercise. Just like a pilot who trained 10 years ago would not land a plane with a trainee on board... you have to do it yourself.
Basinga... for the FI's.
