What a Lieutenant General Does

A lieutenant general is a very important leader in the U.S. military. They command large groups of soldiers, Marines, or airmen. For example, an Army or Marine Corps lieutenant general often leads a "corps." A corps can have between 20,000 and 45,000 troops.

Air Force lieutenant generals command large air forces. They might also lead major commands. These officers also work in top offices at the The Pentagon. They often lead entire departments there.

The United States government sets limits on how many generals can serve at one time. This includes lieutenant generals. For example, the Army has a limit of 231 generals. The Marine Corps has 62, and the Air Force has 198. Only about 25% of these can be three-star generals or higher. The President can change these limits during a war or national emergency.

Getting the Rank

Becoming a lieutenant general is a big deal. It is a temporary rank. Officers usually get this rank when they are chosen for a specific high-level job. Their rank lasts as long as they hold that job.

The President chooses officers for these roles. The Secretary of Defense and the Chairman of the Joint Chiefs of Staff give advice. The Senate must then approve the choice. Most lieutenant general jobs last for three years. Sometimes, they can be extended.

Retirement from Service

Lieutenant generals usually retire after 38 years of service. They must retire the month after their 64th birthday. However, the Secretary of Defense or the President can allow them to serve longer.

Officers often retire earlier than required. This helps younger officers get promoted. There are only a few three-star jobs available. When an officer leaves a three-star position, they usually retire. This makes space for someone new to be promoted.
