You wouldnt know the rank of a D boy unless you had to know. First names and no insignia.Delta or not, would a Sargent first class really have talked to a Captain that way?
It was not uncommon for rangers to provide outer cordon and pull security for Delta raids up through GWOT. A ranger captain wouldnt be saying dick to a dboy about TTPs
And yes, enlisted guys will correct and officer with a quickness in that world. 15-20 years of experience vs 2 years regular army and maybe a year or two with a platoon or an ODA.
I got to work with COL Steele in iraq and he was one of the finest officers and took care of his enlisted guys. This was before he got ran out of the army for killing too many bad guys.
