Except when in the presence of troops, senior officers frequently
address juniors as "Smith" or "Jones" but this does not give the
junior the privilege of addressing the senior in any other way than
his proper title. By the same token, officers of the same grade
generally address one another by their first or last names depending
on the degree of intimacy. The courtesy and respect for others which
govern the conduct of gentlemen are expected to prevail at all times.

Enlisted men are commonly addressed by their last names. Except in
cases where the officer has a blood relationship or a preservice
friendship with an enlisted man, the occasions on which an enlisted
man can properly be called by his first name are extremely rare.
Speaking face to face, it is proper to use either the last name,
alone, or the title of rank, or the last name and any accepted
abbreviation of the title. In calling First Sergeant Brown from among
a group, it would be acceptable to call for "Brown" but better still
"Sergeant Brown." In the Navy, the common practice in addressing Chief
Pharmacists Mate Gale, for instance, would be either "Gale" or
"Chief." On formal occasions, as in calling a senior enlisted man
front and center at a formation, the full military title would be
used: "Chief Bo's'ns Mate Gale and Master Sergeant Brown, front and
center." The longer form of address would also be proper in directing
a third party to report to Master Sergeant White.
