It is very rare that a man should be at once under consideration for both the Medal of Honor, and sainthood.
There seems to be only one other example, which I owe to Deltabravo's posting in the comments of BLACKFIVE. Even looking outside the United States, to degrees on par with the Medal of Honor, there are perishing few. Joan of Arc, Alfred the Great -- him to only some Catholics -- perhaps Olaf or Edwin of Northumbria, perhaps St. George, and not many others.
It's a rare company.
