Could the US army have potentially accepted Mormon units recruited from Utah at any point after 1859-60, to serve as integral combat formations just as black units did during the CW ? otl, Mormons did make a contribution to US combat efforts such as the interpreter Lemuel Spilsbury who served with the cavalry on the plains, and the 7th Inf Div HOURGLASS during WWII, as recruited from the southwest, containing a large no. of Mormons, but how would specifically all-LDS member units have affected things ?
