The Army, in its infinite penny pinching wisdom, chose not to equip the helicopters with air conditioning which is standard equipment on the commercial version of this aircraft. You must remember that this is the same outfit that was buying berets from a Chicomm company to save money.
I see another potential design flaw. If they are going to use these things to patrol our southern border, there is not enough room available for a 7.62 minigun system.
