An aid station is a temporary facility (often a tent, table, or general rest area) established to provide supplies to endurance event participants or medical first aid and provisions during major events, disaster response situations, or military operations.
Aid stations may be divided into sections where the station serves both medical and non-medical functions.
A field hospital is a temporary hospital or mobile medical unit that takes care of casualties on-site before they can be safely transported to more permanent facilities. This term was initially used in military medicine but it has also been used to describe alternate care sites used in disasters and other emergency situations.
A field hospital is a medical staff with a mobile medical kit and, often, a wide tent-like shelter (at times an inflatable structure in modern usage) so that it can be readily set up near the source of casualties. In an urban environment, the field hospital is often established in an easily accessible and highly visible building (such as restaurants, schools, hotels and so on). In the case of an airborne structure, the mobile medical kit is often placed in a normalized container; the container itself is then used as shelter. A field hospital is generally larger than a temporary aid station but smaller than a permanent military hospital.
A military vehicle is any vehicle for land-based military transport and activity, including combat vehicles, both specifically designed for or significantly used by military. Most military vehicles require off-road capabilities and/or vehicle armor, making them heavy. Some have vehicle tracks instead of just wheels; half-tracks have both. Furthermore, some military vehicles are amphibious, constructed for use on land and water, and sometimes also intermediate surfaces.
Military vehicles are almost always camouflaged, or at least painted in inconspicuous color(s). In contrast, under the Geneva Conventions, all non-combatant military vehicles, such as military ambulances and mobile first aid stations, must be properly and clearly marked as such. Under the conventions, when respected, such vehicles are legally immune from deliberate attack by all combatants.
