In major conflicts involving the United States, the percentage of hospital admissions from combat injuries and non-battle illnesses and injuries has varied. Some examples include:

1. World War I (1917-1918): In the United States, approximately 20% of hospital admissions were due to combat injuries, while the majority (80%) were due to non-battle causes such as disease, accidents, and other illnesses.

2. World War II (1941-1945): During World War II, roughly 30% of hospital admissions were attributed to combat injuries, with the remaining 70% resulting from non-combat factors.

3. Korean War (1950-1953): In the Korean War, approximately 25% of hospital admissions were related to combat injuries, with 75% being non-combat related.

4. Vietnam War (1965-1975): In the Vietnam War, it is estimated that around 20-25% of hospital admissions were due to combat injuries, while 75-80% were due to non-combat causes such as infections, environmental conditions, and accidents.

5. Gulf War (1990-1991): During the Gulf War, the proportion of hospital admissions from combat injuries was relatively low, with estimates ranging from 10% to 15%, while non-combat causes accounted for the majority.

6. Operation Iraqi Freedom (2003-2011): In Operation Iraqi Freedom, the percentage of hospital admissions resulting from combat injuries was approximately 15-20%, with non-combat factors contributing to the remaining admissions.

7. Operation Enduring Freedom (2001-2021): In Operation Enduring Freedom (Afghanistan), it is estimated that around 20% of hospital admissions were related to combat injuries, while the majority (80%) were due to non-combat causes.

It's important to note that these percentages can vary depending on the specific conflict, the medical capabilities available, and the nature of the combat operations involved.
