Maybe right now but not forever. Mass production makes things cheaper. Mules (and horses) were abandoned decades ago (almost a century now!) in favor of tractors. Because tractors were cheaper.<p>You have to feed a mule even when you don&#x27;t need it. You have to house it in a climate-controlled building. You have to clean up after it. You have to medicate it, raise it for years until its useful, bury it when it dies.<p>No, animals are vastly more expensive propositions. Especially in a war zone.
