How to tell if an animal makes a good Hewan

So, you wanna make a Hewan? Well, a Hewan could be any animal, provided you could find a reason for it to exist in the war. Not all animals are as cut and dry as, say, a Komodo Dragon. They're strong, have sharp teeth and could kill you with one bite if left untreated. This is due to bacteria. But take an animal like a red panda. They may not be dangerous, but they are very skilled climbers, which, while in a forest or something could be very useful for getting a birds eye view without even having wings!

The More Obvious
So, we all know there are obvious uses, and less obvious uses. Now we'll be briefly covering obvious Hewan traits that would make good use in the war
 * Sharper teeth, claws, etc.
 * Night-vision
 * Flying or breathing underwater.
 * Armor like skin
 * Venom of some sort.


 * Could be updated

The Less Obvious
Ahh, less obvious uses. They're very convenient, nobody expects them. So, why does this matter? Well, the more of these traits an animal possess, the higher population percentage they'll have. You won't see a bunch of sloth Hewan everywhere because they any real convenient use in a war. The most common Hewan type is mammalian, more specifically wolf Hewan. They're good trackers, loyal, and have more primal fighting instincts.
 * Climbing Skills
 * Good tracking skills (Be it sight or, the more popular, smelling)
 * Camouflage (depending on the environment, but since most of the fighting takes place in Russia and north Korea, let's go with snow and ice camouflage, among other environments by them.)
 * High intelligence (May not seem like much, but back in the war Hewan weren't as intelligent as they are now, being far more animalistic back then.)
 * Opposable fingers of any kind.
