As the Navy and Air Force are both branches of the army, they are both equally hard to get into. Also it depends what you like, whether you would like to sail the world with your crew on a Navy Ship, or would you like to repair planes, pilot planes or refuel planes. They are both equally hard to get into, they both require qualifications if you wish to climb the ranks. However Special Ops teams are the hardest to get into but obviously you must already be in a Military Branch if you wish to join a Spec Ops team most likely they will ask you to join if your skills are Sufficient enough for them or your Commanding Officer will recommend you joining them if you "Stand out from the crowd"
From what I heard the Navy or Air Force
It depends on what you want out of it.

The Air Force and Navy have the largest intelligence divisions, so either of them.
Air Force. The Navy has more Ships.
Luftwaffe is a German term for the air force branch of the army. The literal translation is Air Power. Luftwaffe is still used for name of the modern German air force. During WW1, the German air force was not called the Luftwaffe. They were simple the German Air Service. They also had a branch in the Navy called the Marine Air Force.
Military branch (Army, Navy, Air Force, Marine Corp) Psychological Services.

Army, Navy, Air Force and Coast Guard........................
No. It's a sixth branch separate from the existing Army, Navy, Marines, Air Force, and Coast Guard.
That's no so easy to answer. The Army has the largest ground branch. However, the Navy has a subordinate ground branch (the Marine Corps), an air arm, plus a sea arm. The Air Force has the largest air arm of all the branches. The Navy and Air Force both have the capacity to launch nuclear weapons. They all have their strengths in their respective areas.
either coast guard or air force
