Exercise for the reader: Work out what the chances of winning are with each type. (You can take the assumption that the other person's choice is at random if you like, or you can take the assumption that the other person is trying to play tactically also.)

Status of brain: Comatose.

I scribbled this , but I'm not sure if that helps me.

If the opponent's random, chance of winning is 1/2 for the ones that beat 3 thing, 1/3 for the ones that beat 2. Chance of a draw is 1/6.
I'm not sure what tactics there are - I suppose first level would be picking one that beats 3 things rather than 2 (so five men, asteroid or swampland), next step would be assuming your opponent would do that (so probably picking five men since that beats two 3s and a 2 rather than mostly 2s). You could generate a matrix of the probabilities of winning at each level, have an opponent who picks options in proportion to their likelihood of winnning against the previous strategy, and iterate?
