It is unclear what type of uml schema should be created?

Question

UML

There is a test task that says " Describe the scheme (UML) of interaction in the game"
And then there is a description of which element of the game can do with what (whom to kill, how to move, who cannot be killed, etc...)
Question: what type of uml diagram is available, is it Class diagram or Communication diagram? And how to portray this (that, for example, a tank can kill the military, and the military can kill the tank and their own kind of military ...)
