AFH 10-222 Volume 14 1 August 2008 61
3.3. Prefabricated Structures. Prefabricated structures provide a rapid construction
and placement capability. The most commonly used prefabricated
structures are the International Organization for Standardization (ISO) shelters
and ISO shipping containers.
3.3.1. Expandable Tactical ISO Shelters. ISO shelters (Figure 3.6) are not
as vulnerable to blast and fragmentation as tents and provide highly mobile,
environmentally controlled space for a variety of field activities. Several
models are available, including non-expandable, one-side expandable, and
two-side expandable models. Tactical shelters are wired for 60 or 100 amp,
three-phase electrical distribution and are integrated with internal fluorescent
lights, 120 VAC, 20 amp electrical outlets, an external area light, and an interface
for external environmental control units. Although research is constantly
being conducted to develop designs that are capable of resisting the
effects of blast and fragmentation, tactical shelters can be hardened with
sandbags, revetments, berms, concrete barriers, or other methods to provide
some degree of protection. For additional details on the use of tactical shelters,
refer to AFH 10-222, Volume 6. DOD also established a Joint Committee
on Tactical Shelters (JOCATAS) to prevent the duplication of tactical
shelter research and development amongst the services. JOCATAS is also
responsible for approving the DOD Standard Family of Tactical Shelters.
