Address
Formally, the term “General” is always used when referring to a four-star general. However, a number of different terms may refer to them informally, since lower-ranking generals may also be referred to as simply “General”.
Statutory limits

The United States Code explicitly limits the total number of general officers (termed ''

This is set at seven Army generals, two Marine generals, eight Air Force generals, two Space Force generals, six Navy admirals, and two Coast Guard admirals.
Several of these slots are reserved by statute. For example, the two highest-ranking members of each service (the service chief and deputy service chief) are designated as generals. For the Army the

Appointment and tour length

Four-star grades go hand-in-hand with the positions of office to which they are linked, so the rank is temporary; the active rank of general can only be held for so long- though upon retirement, if satisfactory service requirements are met, the general or admiral is normally allowed to hold that rank in retirement, rather than reverting to a lower position, as was formerly usually the case.
[10 USC 601](_blank)
Positions of importance and responsibility: generals and lieutenant generals; admirals and vice admirals Their active rank expires with the expiration of their term of office, which is usually set by statute.
Generals are nominated for the appointment by the

Extensions of the standard tour length can be approved, within statutory limits, by their respective service secretaries, the Secretary of Defense, the President, or Congress but these are rare, as they block other officers from being promoted. Some statutory limits can be waived in times of national emergency or war.
Retirement
Other than voluntary retirement, statute sets a number of mandates for retirement. A general must retire after 40 years of service unless they are reappointed to serve longer. Otherwise all general officers must retire the month after their 64th birthday.
[10 USC 1253](_blank)
Age 64: regular commissioned officers in general and flag officer grades; exception However, the
Secretary of Defense can defer a general's retirement until the officer's 66th birthday
and the President can defer it until the officer's 68th birthday.
To retire at four-star grade, an officer must accumulate at least three years of satisfactory active duty service in that grade, as certified by the Secretary of Defense.
