I’m not a big fans of animals analogies in military affairs. The weapons, even in the hands of the incompetent are too destructive.
I rather like the Prussian, mathematics, physical approach.
They, and the Army have a really good program in ever so old, and true infantry skills.
I was reading about MOH winner Gunny Basilone on Iwo Jima and his directing the taking out of a pillbox. Pure weapon symphony. Using a .30 to close the shutter doors, and having a satchel man walk up beside the gun stream, and blow open the door, then repeating the opening with the mg and a flame thrower, then bring up the mg to gun the japs fleeing the flame thrower.
I prefer the Army’s approach to the Siegfrid line: Line up the pillbox in gun bore of a 175 and fire for effect. The Siegfrid was next to worthless because it was badly under gunned, not enough heavy artillery.
