The MMU is kept readily available 24 hours a day, 365 days a year, to support damaged health-care facilities, or those that require extra capacity due to disasters and emergencies such as floods, fires, or seismic events.

With its own power, oxygen, water, and waste capacity as well as on-board medical consumable and pharmaceutical supplies, the MMU can be completely self-sufficient for up to 72 hours in the event of disaster or other emergency.

For sustained recovery missions requiring space beyond what the 1,100-square-foot hospital facility can provide, the MMU also comes equipped with an optional 6,000-square-foot tented structure. This structure has its own heat and lighting, and can be constructed around the perimeter of the hospital trailer. It can be used to provide limited shelter, treat, and triage large numbers of minor ill or injured people.
