Offensive and Defensive Combat Spread. DCS has the wing 1nm abeam and 0-1000ft above. OCS was looser. Pretty much what you described.
Yes, that's the same definition as "tactical formation" in the USAF. Love how the USN and USAF can have all completely different words to describe the same canon of things.
