..... perhaps maybe some of those in the military may be nuts or suicidal/homocidal.....

I shall divide your question in two parts to respond:

First off, we may find nuts or suicidal/homicidal in any segment of society or professional capacity. That is no reason to deny rights of all.
That is one of the liberals main arguments for gun control.

..., but shouldn’t you have armed guards on the base, at the least?...

In my humble opinion the response to the first part of the query also answers the second part

And honestly, THERE SHOULD BE ARMED PERSONNEL ON BASE!

Yes. I thought I had made that point clear enough.
