I agree, at least arm the ones on guard duty. Everyone doesn’t need to be armed but if you are on guard duty yes you need to be armed today. Maybe not so much back in the 60’s 70’s but the world today is vastly different.
The purpose of guards is to hand out DWI’s and drunk-n-disorderly charges on Friday/Saturday night - this is the priority. My niece recently graduated law school and interned with the JAG corp. She said you would not believe the guys getting charges at the gate fresh back from deployment.
