What is referred to as the ‘gun free’ policy in relation to US military bases .. "can be traced back to Department of Defense (DoD) Directive 5210.56, signed into effect .. under President George H.W. Bush." Relevant to the cartoon, the policy stated that, “DoD personnel regularly engaged in law enforcement or security duties shall be armed.” .. (text in quotes from this article)
There aren’t armed people walking around base. MPs have pistols but there aren’t a lot of them. In fact military bases are more vulnerable than other places because nobody has the right to keep arms on post. You need command approval to even keep a gun in your locker.
So whoever wrote this comic has shown they don’t actually know anything about the military. :/
The comment though. Nailed it.
