Well, thanks. Maybe I misunderstood my friend about CWO Gunner. It is hard enough for me to judge firmly in this question as the Russian military has nothing similar to CWO corps, whatever branch one may take to consideration. And when we here spell something in "mustang" meaning, it seems to be the former conscript who took all five years of naval college (age limit to enter is 23) after his enlisted obligation. We call him "V/S", short from "Prior Service" in Russian. There are officers without degree here, a kind of direct commissioning, but a figure I have met is they are about 0.3% of all officers corps and their top possible rank is LtCdr/Maj. All the others boast a degree given in naval colleges, mostly Electrical Engineering or Maritime Engineering majors. So CWO and even CPO personnell of USN have here nothing to compare with.
What about strike fighter squadron, we have just one unit - 279th Carrier Air Regiment, whose two squadrons are equipped with Su-33s (interceptors), MiG-29Ks (strike fighters) and Su-25UTG (trainers), and AFAIK most of its pilots are of rank LtCol and have so-called "Master Military Pilot" qual, so it is quite an elite unit. All important decisions - load in mission among them - are those of Colonels - a sqdn COs or Regimental CO and XO.
