WHY did the Marine Corps eliminate push-ups from the PFT?

Becuase imo pullups are a better show of practical strength. Using your shoulders/ back to carry loads or pick up and carry people seems more worthwhile then pushups. I dnno if thats the reason or not but thats my opinion. Also the Marines dont require continuious pullups. You can stop and rest or switch your gfip. The only thing is you cant drop off the bar. If you rest or switch grip u have to hang while doing it
