John Maynard Smith produced some interesting game theory models (ESS and Hawk-Dove game) to describe how animals compete for limited resources in a restricted environment.

Simply put,

-Doves never fight.
-Hawks will always fight.
-Retaliators fight against hawks and share with doves.

This game could be applied to competing agencies with the military/government to show how some adapt, some survive, and some fail.
