Army or Marines? Can't decide.?

Okay, well at first I was going to join the Marines. So I started to do some research. Turns out the USMC only pilots Cobras. I want to fly but the Apache-64(u). I want to join the Marines for pride a good challenge and to say I'm a United States Marine. But I want to join the Army because a lot of my family has been in the Army for many years and they have the thing I want (To fly the Apache). But the Marines because I also want to be a Scout Sniper. Now it seems like I have gotten all of these ideas from games. Some what true. But I need help on this. If I fail at becoming a WO or CWO in the Army and end up 11B then I would rather be a Marine and thats the thing...just so many things to choose.
