Last 2013, the U.S. Air Force used 700 shipping containers to build a Military Operations in Urban Terrain (MOUT) training facility because it can easily modify it to resemble a city. And last 2019, they also used it to have a check-in facility in their training range. They place it, pushed together, seal it, and connect all shipping containers within a day. And when they were done with the training, they just disassembled it, put it in the truck, and off to the next destination.

Here are the uses of shipping containers in the military:

• Secured storage - Shipping containers are made from Corten Steel which is known as “weathered steel” for it can resist the corrosive effects of fog, snow, rain, ice, and other meteorological conditions. Plus, anything you place inside won’t be easily stolen or damaged.
• Office facility - The military needs an office to work on their paper and document related tasks. Using a container gives them a proper place to install a data center or a central location for planning every operation they will have. And a perfect mobile facility to protect every stored data equipment used.
• Versatile barracks - It is a great portable housing for every deployed military. It gives them an efficient and comfortable place to stay in any location that they will be, for they can install heating and cooling systems or other amenities that they need.
• Barriers used in training operations - Cargo containers can resist any major damage without ruining their structure; that is why it is a perfect barricade during a military training exercise.
