Unless that's something new, no one calls LCDR's "Commander" other than they themselves. There was an old joke that they were "phone Commanders", as in, they answered their phone as CDR So-and-so. In a very informal setting, they might be called CDR to stroke their ego, but rarely. I know during my 30 years in, I never did.
In my time in even the CDR held the greatest respect for the Senior enlisted man.
Heck, we have you surrounded ;)
Lt. Col Oliver North has referred to himself as a “Telephone Col.”
sometimes LCDR’s are referred to as Commander when they are serving as XO of a ship. Just as the CO is always referred to as Captain, even though he may be a LT, LCDR or CDR.
