Who was the first soldier to accomplish a given task, such as entering Berlin in World War II, first killed on D-Day, or who was the "wealthiest," "youngest," or "oldest" soldier in U.S. Army history.

As a matter of policy, unless an official announcement of known facts is issued, the Center of Military History refrains from sanctioning claims involving "firsts" or the "most" because they often are difficult to substantiate and frequently are contested by other claimants.
