The rate of development in the commercial sector has frequently exceeded that in the military sector, leading to more potent capabilities at lower costs (take communications, for instance). Military applications look for COTS (commercially available off-the-shelf) technology that may meet their strict requirements so they can get some of the benefits. The military standard for D-sub connections is M24308. Ruggedized tablets, laptops, voice and data communication systems, GPS receivers and hubs, and mobile power supply units are examples of devices that often use M24308 D-sub connections. Mil-COTS connections must be able to survive extreme temperature changes, corrosion, high impact shock, and other combat-related situations. They are made to work at a variety of temperatures.
