I dont think Navy has an infantry though.
Don't get me wrong, and it is my personal opinion based on what I have experienced over the past 12 years of my career in the military, the training has really slacked off, especially since the mid 2000's for new soldiers.
I personally came from a time when taunting, pushing, and physical correction was common during basic training. It doesn't happen that way anymore. LOL
Most of the medical MOS of the air force is also done along side with the army in San Antonio on Ft. Sam Houston as well.
