Choosing among active duty, the National Guard and the Reserves is one of the most important decisions a prospective service member can make. While all three paths offer the opportunity to serve, they differ in terms of time commitment, family impact, benefits, career flexibility and retirement options. Understanding how each component fits into your professional and personal goals can help you select the military service option that best aligns with your desired lifestyle, financial priorities, and long-term plans.
Service to country can take many forms. From full-time active-duty service to the community-focused mission of the National Guard or the flexibility of the Reserves, each option provides a unique way to serve while supporting different personal and professional aspirations. Before making a decision, it's important to understand how each path can affect your family life, benefits, career opportunities and long-term financial future.
Think of this as full-time military service. It’s usually your primary job, though some service members also have part-time jobs, and you serve at the discretion of your branch of service and the president as commander in chief. You are the main defenders of our country.
Joining the reserves essentially means you’re signing up for part-time military service — though some reservists are full time. Often, reservists will serve full time for three to four years and then go back to part time. The Reserves are funded by the federal government, just like other U.S. armed forces, and the president is the commander in chief.
The National Guard is a little bit different. During peace time, members of the National Guard work for the governor of their state. For example, you may see National Guard members responding to natural disasters like floods, hurricanes and at times civil unrest when local authorities need their support.
But the National Guard can also be activated to federal service and serve alongside active-duty forces and the Reserves. In those instances, they answer to the president.
Usually, those in the National Guard and the Reserves serve one weekend a month and two weeks a year. But that’s not always the case.
Some reservists and National Guard members serve full time.
In times of conflict, it’s common to see active duty serving right alongside reservists and National Guard members.
There’s a reason people say serving your country is a sacrifice not only for the service member but also for their family. In general, active-duty service members are gone more often than National Guard or Reserves members. But it’s common for National Guard or Reserves members to also sacrifice family time because they are working two jobs, one civilian and one military. It requires some delicate balancing and time management, and can mean less time for your family and your civilian life.
But there are protections for your civilian job while you perform your military service thanks to the USERRA, or Uniformed Services Employment and Reemployment Rights Act Opens in a New Window.
But even though your job is protected, that doesn’t mean work won’t pile up. Often, reservists or National Guard members find they have to work hard to catch up when they return to the office after serving. That can mean sacrificing even more time away from loved ones.
Working overtime isn’t the only sacrifice, however. Reservists and National Guard members also often must give up family time to travel. It’s not uncommon, for example, for members of the Reserves to have to drill in another state. Traveling back and forth can eat into family time and add stress.
When a service member is assigned to a new duty station or base, it’s called a permanent change of station, or PCS. On average, active-duty service members move about every three to four years. In the National Guard or Reserves, you aren’t going to move unless you really want to.
The Reserves and National Guard offer a more stable lifestyle, which is what many people want. They want to establish roots and let their kids grow up in one location.
It’s important to protect your family and ensure you have the benefits you need. Things like medical, dental, vision and life insurance are the core of your financial security.
Active-duty service members receive those as part of their service. Members of the National Guard and reservists face a choice, however. They have certain military benefits, but they also probably have benefits through their civilian employer. They need to consider which policy is better and consider when they are covered and who can be covered.
For example, TRICARE’s Active Duty Dental Program is an option for National Guard and Reserves members but only in certain situations, such as being on federally funded orders for more than 30 days. And it’s only for the military member, meaning the family is not covered. In that case, using civilian benefits for dental might better fit your family’s needs. Dental and vision insurance can help you save on preventative care and avoid costly medical issues in the future, so it’s important to make sure you have the coverage you need.
There’s also TRICARE Reserve Select, and in some states, National Guard members can qualify to have their TRS premiums paid for by the state. These benefits can be great, but it’s still important to compare them against civilian insurance policies.
Active-duty service members are eligible for Servicemembers’ Group Life Insurance, or SGLI. But it might not be enough for you and your family.
While SGLI is available to members of the National Guard and Reserves, there are eligibility requirements Opens in a New Window. There may be periods where you’re not covered by SGLI, so you’ll need to protect your family with a private life insurance policy. Another option to consider is spousal life insurance.
When you retire from active duty, you get to keep TRICARE and begin to receive your military pension.
When you retire from the National Guard or Reserves, you also get the pension and TRICARE benefits, but generally not until you turn 60.
National Guard and Reserves retirement can be confusing, so it’s important to understand how to earn points and maximize your retirement income.
For the most part, you’ll stick with what you originally start with. But the opportunity to transfer back and forth is becoming more available. In fact, many reservists and National Guard members were once active duty. You can also use the Reserves or National Guard as a job anchor. If you find yourself in between civilian jobs, it might be a perfect time to advance your military career by going to NCO Academy or taking a year of orders for a staff position you’ve been needing.
