I assume you're asking about World War II. Are you asking about the numbers of American -- or all national forces -- in those arenas?

I suggest you check your library for books on this subject. That would be the most efficient way of researching these detailed questions.

To find the specific information you're looking for, here are the steps you can follow:

1. Start by checking reputable sources such as history books, academic journals, or official military records.
2. For the number of soldiers in the Pacific and Europe during WWII, you can consult books specifically focused on these theaters or general histories of the war. Some well-regarded books on this topic include "The Pacific" by Hugh Ambrose and "D-Day: The Battle for Normandy" by Antony Beevor.
3. To learn about the type of warfare in each arena, you can look for books or articles that discuss the military strategies and tactics employed in the Pacific and European theaters. "The Pacific War" by John Costello and "The Second World War" by John Keegan are good starting points.
4. Finding out when soldiers left each arena and the length of their terms can also be found in books that document the various military campaigns and the timelines of troop deployments and rotations. You may want to look for books focused on specific battles or campaigns, or broader histories of the war.
5. Regarding the lasting conditions experienced by soldiers after returning from World War II, including post-traumatic conditions, you can explore books and scholarly articles on the psychological effects of war, post-war adjustments, and veterans' experiences. "The War After the War: The Struggle for Credibility during America’s Exit from Vietnam" by Johannes Kadura could be a starting point.
6. The number of soldiers who returned or were killed would likely be available in official military records or statistics compiled by relevant government agencies. Additionally, you can consult books or online sources that specifically address casualties and the overall number of service members involved in the conflict.
