I am a five foot tall female and I can understand exactly why I could not protect a tall guy with my body. Shame these ladies could not see that.
Go back in the video and it appears that she chose to inject herself as a protector...AND PROTECTING TRUMP PERSONALLY WAS NOT HER JOB.
But, you could pilot a drone, watch the back of a building, monitor security cameras, manage communications, etc. Every one is a critical job.
