The Mission of the MSALTS (below) is to provide the Office of the Director, Operational Test and Evaluation (DOT&E) Center for Countermeasures (CCM) and its customers with a portable Infrared/Ultraviolet (IR/UV) open-air missile simulator to support multiple tests of Directed IR Countermeasures (DIRCM) and/or Missile Warning Systems (MWS).

When you couple the human aspects of stress on the people undergoing the simulation, it is easy to see how the heat load would climb, along with moisture inside a closed rigid wall shelter.
