What's the duration of enlistment in different military branches?

I've been looking into the post-high school military path, and one thing I can't seem to find a clear answer on is how long the enlistment period typically is in different branches of the military. Does anyone here have any insight on this? How does it impact life post-service?

Typically, the average minimum lengths of enlistment contracts in the active-duty military branches are as follows:

- Air Force: 4 years

- Army: 4 years

- Coast Guard: 4 years

- Marine Corps: 4 years

- Navy: 4 years

- Space Force: As the newest branch, the Space Force is something of a unique case, and its exact enlistment term varies.

It's essential to remember that while these terms represent the active-duty minimums, there are often reserve commitments beyond that period. For example, a 4-year enlistment usually includes an additional 4 years in the Individual Ready Reserve (IRR). During this time, members no longer have to participate in drill or other activities but could be called back to active duty in an emergency.

Serving in the military can significantly impact life after service. For example, veterans often have access to benefits such as the GI Bill which can help with college tuition fees, and VA loans which can assist in buying a home. Besides financial benefits, many veterans also find that their military service has equipped them with valuable skills like leadership, discipline, teamwork, and problem-solving. However, transition back into civilian life can also bring challenges, and each individual's experience will vary depending on a host of factors including the nature of their service, personal circumstances, and supports available to them.
