General Hammond seems to always make bad decisions. He nearly let Earth be destroyed a few times, and he isn't very good at strategy.
In the image above Hammond is playing a game of Connect 4 against an unknown opponent (Jack has just arrived) and yet neither side seems to be winning. With all of his experience as a US General this should be a simple matter for Hammond, yet he seems to be struggling with his opponent.
Even Bra'tac is condescending toward General Hammond, never referring to him with respect but instead calling him 'Hammond of Texas', as if to mock him.
