Yes, the Air Corps was a branch of the US Army before and during World War 2. In 1947 it became an independent branch of the military: the US Air Force.
The number and strength of the various corps changed over time. The Union had 25 numbered corps, plus an ambulance corps, balloon, cavalry, and telegraph corps. Not all of these were in operations at the same time. Not all of the Confederate Army was divided into corps. The Army of Northern Virginia had four regular corps and one cavalry corps. The Army of Tennessee had 3 corps. The Confederates had about 13 small armies which might be considered as corps. Most of these armies did not operate throughout the war; instead they were broken off of other units and later merged again.
The officer ranks are both the same. However the enlisted ranks are different. The Army also has Warrant Officers where as the Air Force does not.
See website: Pearl Harbor Attack See website: US Military Ranks (US Army, US Navy) The US Air Force did NOT exist during WW2. It was part of the US Army. The US Marine Corps is part of the US Navy. However, it's (officer) rank structure is the same as the US Army's.
The same as other industrial nations; mostly WW1 style bi-planes (two wings). Like the US, the Japanese Air Force was part of the Army.
As part of Australia's Army, Navy and Air Force, they used the same as those of servicemen from the other states and territories.
In ascending order:Second LieutenantFirst LieutenantCaptainMajorLieutenant ColonelColonelBrigadier GeneralMajor GeneralLieutenant GeneralGeneralGeneral of the Army*Note that the United States Air Force and United States Marine Corps use the same rank structure for their officers, except for General of the Army. The Air Force does have an equivalent rank (General of the Air Force), but the Marine Corps does not. General of the Army/General of the Air Force/Admiral of the Navy is a special wartime rank, and is not normally in use during peacetime.
The same as with a regular military: to defeat the enemy. Only the strategy & tactics are different, because a guerrilla force does NOT have an Air Force, Navy, Marine Corps, nor a regular Army.
The Marines are a component of the Department of the Navy, and the Army is a component of the Department of the Army. Also, the Army and Marine Corps have different force structures, missions, and cultural/heritage items.
they both had to fight the enemy in WW1 and WW2
All of them. Air Force and Navy pilots penetrate the furthest into enemy territory than anyone else. The Air Force has their Tacp, Pararescue, and Security Police personnel, who are often in harm's way, and it's much the same with units such as the Navy's Construction Battalions, not to mention that, as the Marine Corps does not have certain services (such as a medical corps), those services are provided by Navy personnel, who will be attached to Marine units. Air strikes are called in by Air Force Tacp personnel. So it's not just the Army and Marine Corps.

It represents a second award of the same medal. Oak leaf clusters are only used by the Army and Air Force. The Navy, Marine Corps and Coast Guard use stars.
The officer ranks are both the same. However the enlisted ranks are different. The Army also has Warrant Officers where as the Air Force does not.
For the US Army, it's a bronze oak leaf. The same insignia is used by Majors in the Air Force and Marine Corps, and by those holding the rank of Lieutenant Commander in the Navy and Coast Guard while wearing certain uniforms.
No, it is not the same thing. The USMC has developed a full system to train their personnel in hand to hand combat.

SSGT is a military rank in the US Air Force that means Staff Sergeant. In the US Air Force, it is used to signify an individual in the pay grade of E-5. In the Army and Marine Corp, the same name and abbreviation are used, but in this case, they signify someone in the pay grade of E-6.
