How do I decide which airframe to select, assuming I am fortunate enough to have a choice?

Excellent question. The short answer: You can’t go wrong with any of them.

Your options will be UH60, CH47, AH64, or C-12.

The CH47 is an awesome piece of machinery. >50,000 Max GWT, gobs of power, lots of flying. It’s a beast.

AH64: Guns are cool. The culture is a little... different, but it’s a sexy aircraft. Flying around and shooting is a neat mission set.

H60: Swiss Army knife of the Army. A lot of diversity in your mission. I flew for 60’s for 5 years and loved them. 3900 horsepower, and the M model is pretty sharp.

C-12: I’m a fixed wing guy now and HIGHLY recommend the FW stuff. MI/ISR stuff might get a little boring, but VIP is a blast.

I’m happy to delve in deeper, but I never met a guy who hated his assigned aircraft. You can’t go wrong.

Good luck!

You are putting the cart before the horse. Stay focused on the 25 meter target, successfully pass WOC, then concentrate on flight school. How do you eat an elephant? One bite at a time.

Your selection will be based on two things. Class rank and aircraft availability. Last few selections have been apache heavy with see a and a few Chinooks. A month ago, no apaches for two selections. So understand that while you can't control what the army will have available, if they only have 2 of something you want, you damn well better be at/near the top.
And to the original question, it's all about the mission. That should be your single deciding factor.what do you want to wake up everyday and do.
