21. Refrigeration/Air conditioning technician (Marine Corps, Air Force)
The Air Force has airmen trained as standard HVAC technicians. The Marine Corps version is a little different with some Marines being trained in refrigeration and air conditioning while others handle heating systems. In either case, these service members are the ones called when the desert is too hot or the mountains are too cold.
