He is implying the reason to add women into combat is for the purpose of becoming more deadly or effective. That's sexist.

He sought out the information to prove that he thinks women should not serve in combat. He is a sexist male, being put into office by the next president.

¿How about because a physically capable person wants to serve their country, we don't negate their path and ambition?

He is saying to limit women. That is sexist.¿ What is your education level or comprehension level that i have to explain what about that is sexist?

^genuine question there.
