Military size honestly signals a state’s fighting strength just as animal weapons do

Evidence

States invest in militaries to the extent that they are able, but the sizes of militaries vary widely from country to country. As with beetle horns, caribou antlers, and fiddler crab claws, the relative size of a state’s military provides an honest signal of its fighting strength: a perfect tool for deterrence. — Emlen, Douglas J, Animal Weapons_ The Evolution of Battle, 557
