Two imperialistic power bide for control of great plains. Hippos have inferior manpower and military technology, therefore they make up for their weak point with raw industrial power and physical strength. their uniform contain loose battle dress and big hat to protect their skin from direct sunlight. they are called golden hawk, from their old national animal that appears on their banner.

On the other hands, National Revolutionary Republic has an advantage on manpower and military tech, so they could apply more radical solution to deal with hippo's overwhelming individual combat ability, shown here as semi-automatic rifle with detachable box magazine. compared to hand-held gattling gun with bipod that is yielded by a hippo here. they also utilize spike bayonet to punch through hippo's hard skin. they are called red elephants, or reds.

At first, I thought of red hippopotamus cuz they are little use of hippo as a national or ideological mascot. but circumstances.
