With respect to fighting wars? No. The military has a couple stand out statistics, first being that most enlisted are of generational servitude while most officers are from opportunity (college recruitment). That means most people enlisted have a relative that served first. Second is that most enlistments come from the poorer part of the country, specifically the South and Midwest. The diversity of the military largely tracks those geographies. Officers similarly reflect where their volunteer pool comes from. That said, the modern upper echelon of US society have a pretty quiet yet thick disdain for military service. They'd probably never let their kids do it.
