The meaning of friendship

Many kingdom-related thoughts are more far-reaching than this one.  However, I have several things pressing and simply wanted to share this logo, lifted from a university web page.

I ask this:  what is the meaning of this “friendship”?  I suspect that the answer is more about paperwork and processes than about philosophy . . . but what is it for a university (in this case, a “Christian” one) to proclaim it is friendly to the military?
