How is military prison different than regular prison? How many American...

...soldiers are in military prison? What are some reasons they end up in them?
The reason I am asking is because the movie 'The Dirty Dozen' is on TV. It's about the 12 prisoners sent behind the German front lines during WW2.

yes you are still required to adhere to military discipline, the Correctional officers are all Non-commissioned officers (sergeants E-5 to E-9) and as such are required to be physically fit and meet the army requirements for physical fitness to my knowledge there are no such physical requirements in state of federal prison systems.. Army noncoms are also required to attend the NCO academy for promotion to higher grade.. All military prisoners are reduced in grade to E-1 that is private and are subject to the Uniform Code of Military Justice until discharged which is at release at which time they receive dishonorable dishcharge .
The prison at Ft Leavenworth KS and Mannheim Germany are kept to military standards at all times and discipline is maintained at the same level as entry level trainees to basic training (that is total control), I do not know the number of incarcerated military members in military prisons.U.S. Disciplinary Barracks
Fort Leavenworth, Kansas
The United States Disciplinary Barracks (USDB) at Fort Leavenworth, Kansas is the only maximum security prison in the Department of Defense. It is the oldest penal institution in continuous operation in the federal system. Operations at the prison started in May 1875 and have continued to this date. Its mission is to incarcerate U.S. military prisoners sentenced to long terms of confinement, and conduct correctional and treatment programs to maintain good order and discipline and reduce recidivism upon release; and, on order, provide trained and ready Soldiers to conduct world-wide deployments in support of contingency operations.

The American Correctional Association (ACA) has continuously accredited the USDB since 1988. The new USDB will be considered for re-accreditation by the ACA in February 2006. To receive accreditation the USDB must meet or exceed more than 500 standards set by the Association.

With the opening of the new USDB in September 2002, operations continue in a state-of-the-art correctional facility. Groundbreaking for the new facility took place in June 1998 and the facility was turned over to the Army on August 1, 2002.

The 504-cell facility cost $67.8 million to construct. The design is based upon modern prison standards modified to fit the unique military mission requirements of the USDB.

The old USDB covered 12 ½ acres and was surrounded by a rock wall that varied in height from 14 to 41 feet; it had a 10-acre fenced outside recreation area. The new USDB encompasses about 51 acres and is located on the northern part of Fort Leavenworth on the site of the former USDB Farm Colony. The new USDB is surrounded by two 14-foot fences and contains an open-air recreation yard.

The new facility is divided into two zones. One zone houses the general population inmates in three main housing units. The other zone, separated from inmate housing, contains the command group, directorates of inmate administration, treatment programs, vocational training, pastoral care as well as health and dental clinics and other inmate support services. A Special Housing Unit is also part of the support complex. Referred to as the SHU, the unit houses receptees, maximum custody, administratively segregated inmates and those inmates sentenced to death. The SHU can accommodate up to 95 inmates.

There are three housing units for inmate housing. Each housing unit accommodates up to 142 inmates and is made up of two “pods,” which are two-tiered triangular shaped domiciles with an open-air center area containing pay phones, televisions and chairs. One control center, located between the two-tiered triangular shaped domiciles, manages each housing unit.
