Tents usually comprise sheets of fabric and a framework that is made of wood or metal and ropes. The poles and ropes hold the fabric in place above a groundsheet which may be made of a more durable or a harder material than the sheet which makes up the roof of the tent.
For example, one of the main purposes of the roof material in the tent may be to prevent rain and provide shelter. The groundsheet, meanwhile, will also have to prevent water from seeping into those staying in the military pavilion.

Thanks to the portability of even large-sized tents, many armies use these pieces of camping equipment, although they wouldn't be classed as "camping equipment" when used to accommodate platoons, companies, and regiments in the Armed Forces of any nation. They are used to house field hospitals by many armies.
They often have the ability to accommodate air-condition devices, as well as medical equipment. The US Armed Forces have operating procedures and quality controls when it comes to a tent setup and maintenance. Tents can be expanded or added to and can be rapidly deployed, much like the armed forces they are there to accommodate.
The temporary nature of the tent also means that an occupying force's presence in an area can be less psychologically debilitating to a people, enabling them to understand that the armed force will not be a permanent presence, but is only there to offer temporary relief.
