Honestly, the emphasis on tactical jujitsu seems oddly misplaced to me. Both the Romans and the United States have generally won their wars the same way: by bludgeoning an opponent with superior materiel until they collapse.

I think the mistake is viewing this approach as artless or vapid, reducing it to 'human waves.' Instead, leveraging overwhelming logistical and materiel superiority is difficult, it demands a lot from soldiers and officers - crucially demands which don't fit more simplistic models of masculinity.
