Living the dream
Even assault support helo guys stand alert. I've never been tasked with Alert 5 (you are sitting in the aircraft, rotors turning, awaiting launch order) but I have stood Alert 30 for CASEVAC (taxied in less than 15 - booyah!). I'd say the two most common we do are 30 and 120.
Do you add in the obligitory "phrogs are always 15-20 minutes late" on top of this, or is that already factored in?
