Tearful scenes played out across Southern California last week as thousands of Marines from the 11th Marine Expeditionary Unit boarded the USS Boxer amphibious assault ship and deployed to the Middle East amid rising tensions with Iran. Families hugged, waved, and struggled with the uncertainty of the mission and the suddenness of the departure as the Pentagon bolstered forces in the region.

Why it matters

For military families, the deployment brings long stretches apart, worry, and the hope that their loved ones return safely.
