There is no hard answer to that, as pecentages vary widely between the armies of the countries involved, between the various theaters of war, and between army, navy and air force.
A very global figure is that about 30-40% of Allied troops were combat troops and 60-70% were support troops. Because of the way the war in Western Europe progressed, it is probable that the support troops there did indeed see little or no battle, but in other theatres like for instance the Phillippines the figure will have been much different, but no-one was counting then.
In Germany and Japan, it was the other way around, certainly because the combat soldiers could in the end only be replaced by support unit soldiers, and both armies usually got orders to stand and fight instead of regroup. Some 80% of them were at some point engaged in combat actions.
Russian troops on the defence in 1941-1943 probably also had some 75-80% engaged in combat action, which may have gone down to about 65-70% as they got properly organized and started to push back the Germans.
These differences are also reflected in the death rates: 2.5 to 5% for the Allied armies vs. 25-30% for the Russian, German and Japanese armies.

The combat at Gallipoli during World War I was marked by trench warfare, characterized by brutal and static fighting. Allied forces, primarily British and ANZAC troops, faced entrenched Ottoman defenders in a rugged landscape, leading to heavy casualties on both sides. The campaign involved land assaults, naval operations, and fierce hand-to-hand combat in challenging conditions, ultimately resulting in a costly stalemate and the withdrawal of Allied forces in January 1916.
Approximately 16 million American service men and women served in the armed forces during World War II. This included members of the Army, Navy, Marine Corps, Coast Guard, and the Merchant Marine. The war effort mobilized a significant portion of the U.S. population, with many serving in combat roles while others supported military operations through various support roles.
During World War II, the P-51 Mustang had a higher kill ratio than the Me 262 in air combat engagements.
Gas attacks on military forces during combat were not commonly used during World War 2. One of the few fronts was in China by the Japanese.

During World War II, approximately 350,000 American women served in the Armed Forces, with around 16,000 women seeing combat duty. They primarily served in roles such as nurses, support staff, and in auxiliary units, with some women participating directly in combat situations, particularly in the Army Nurse Corps and the Women Airforce Service Pilots (WASP). Their contributions were crucial to the war effort, despite the limited combat roles available to them at the time.
