Two were sworn to defend.

Yet again, American Soldiers were killed by a lunatic gunman. This time, two of them in an IHOP.  Sidearms and fixed bladed knives should be PART OF THE UNIFORM for ALL SERVICEMEN.
Yes, it would require more training.  So what?  Add it to Basic Training to come right after Basic Rifle Marksmanship.  Expand the Hand to Hand training as well.  Give them an extra 2 weeks training during Boot Camp for this.  But if you can’t trust them to be Armed and Responsible, then they should be in the Service to begin with.

Part of the Uniform.  Always on them.  Always.
