Military computers are built with parts and electronics that can withstand the challenging environments of military operations – the type of conditions where consumer-grade equipment would quickly break down. Military computers have protective enclosures that help to prevent ingress of water, dust, sand and dirt. Noncorrosive materials and coatings protect the electronics from the effects of high humidity and salt mist. Shock-absorbing parts help to mitigate the impact of shock and vibration. And heavy-duty components enable superior and continual performance despite exposure to temperatures that range from below freezing to 50°C and higher.
