Your service member’s deployment can bring up many emotions. You may feel pride in your loved one’s service to their country, concern for their safety and stress over the many unknowns.

You can ease some of your worries by learning what to expect, preparing for the changes that deployment may bring, and locating available support for your service member and their family.

What is a military deployment?

A military deployment is the movement of armed forces to support a certain mission. Not all deployments are combat related. Service members may be deployed to support an enduring mission, provide humanitarian aid, to assist in the evacuation of U.S. citizens, to restore peace to a region or to provide increased security.

What to know about deployment

A military deployment spans the time before and after the actual period when the service member is away. The phases of what is called the “deployment cycle” are:

  • Predeployment. This is the preparation stage. Your service member will undergo training, briefings, medical evaluations and counseling before leaving on their mission. Your service member and family will also prepare logistically, financially, legally and emotionally for the deployment during this period. This is a busy and sometimes emotional time as everyone prepares for the change ahead.
  • Deployment. A deployment starts when your service member leaves their home installation. Deployments can be of varying durations depending on the mission. Saying goodbye and being apart can be hard, but keep in mind that this is what your service member has been training for. Your service member is very well prepared and focused on the mission.
  • Reunion and reintegration. Believe it or not, this starts before your service member returns. They will complete post-deployment requirements before they leave their deployed location and continue with additional requirements once they return. This can include scheduled briefings and health screenings once they arrive home. This period can be joyful but expect some bumps along the way as everyone readjusts to life together and your service member reintegrates into their home, work and community life.
