How can we changed E9 to E7
you cannot...thats why the air force has super grades e8 and e9...
It's a situation which could only happen theoretically. Once you've reached the pay grade of E9, you're on the verge of retirement, and are well beyond the point of being eligible to become a Commissioned Officer.

E... what? There are nine enlisted pay grades, E1 through E9, plus the rank of Sergeant Major of the Army, which is technically E9, but gets paid at a higher scale than other E9 ranks. Time in service is also a factor in determining a soldier's base pay.
the lesser known E9 rank is Sergeant Major of the Marine Corps.
