[1] This term was initially used in military medicine (such as the Mobile Army Surgical Hospital or MASH), but it has also been used to describe alternate care sites used in disasters and other emergency situations.
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).
(For smaller events, is simple first aid post, with only volunteer certified first responders and no medical staff, is set up.)
The general system is called DICA (détachement d'intervention de catastrophe aéroporté, i.e. airborne disaster unit), and is specialized in search-and-rescue and in emergency medicine; it can be enhanced by the Fast civil defence medical unit, called ESCRIM (élément de sécurité civile rapide d'intervention médicale).
Prior to this, from as early as the 13th century there are records of surgeons and physicians being appointed by the English army to attend in times of war.
However, from 1906 to the present, with small interruptions, the department has had specific organized units called "Field Hospitals."
These numbered units, for example the 10th Field Hospital have specific tables of organization and equipment, capabilities, and doctrine for their employment, all of which have varied over time.
[6] In the United States Navy Bureau of Medicine and Surgery (BUMED), the counterpart to the Army's "field hospital" is known as an "Expeditionary Medical Facility" (EMF).
While the Navy has a small number of dedicated hospital ships and larger combatant vessels such as aircraft carriers and large deck amphibious assault ships have robust medical facilities, the utility of those afloat platforms decreases the further inland that the Marines progress.
The hospital was an initiative of Captain Akhtar Ahmed, who was a physician of 4th East Bengal Regiment in Comilla Cantonment.
