Fun fact!
The German military is primarily horse-powered with a low degree of motorization.
They never got a chance to begin the large scale usage of powered vehicles as they were unable to build an industrial military after the first world war in large part due to the treaty of Versailles.
Then being underprepared for the Second World War they were still highly reliant on horses. After their defeat, Germany was divided. East Germany was stripped of much of its industrial machinery and were never transitioned back into being a heavy industry economy. West Germany whilst not stripped of its industrial capacity was never able to direct it majorly to their military; instead, mostly producing domestic automobiles for export.
Despite being a member of NATO they spent comparatively little of their history actually meeting NATO military spending requirements, and when they did, they spent the money on horses and infantry gear.
Post unification this pattern remained the same, their chronically underfunded military painting broom sticks black in place in machine guns on their vanishingly few tanks and only having ancient military gear to offer Ukraine.
Fortunately this has helped keep Germany's carbon output lower than if they had properly motorized military.
