Obviously the shield is a symbol of protection. I would have to research the checkered pattern - that has some meaning. The torch is the carrying of/guarding of information - reaches back to the Greek "cults" following Prometheus who started the olympic tradition of passing the torch. The lightning bolt, I am shooting a bit from the hip with - but would symbolize authority and justice held by the seat of Zeus, Perun, or the several others who held the high seat within their respective pantheon. Typically this is used as a "from the blue" lightning strike to symbolize that nothing is exempt from the almighty. Omnipresence/omnipotence.

The double-sided key is the more curious one. "When you stare into the abyss, the abyss stares back." Ratatoskr - the messenger of the Tree of Life, Ygdrassil, who serves as the messenger between mortals and gods. I'm using terms I am more familiar with, but basically that the key represents a double-edged sword and a role caught between two sides of the same door. Taken with the checkering and how it is an inverted to illustrate mismatch or conflict/challenge, the whole of the symbol basically boils down to:

"Through Knowledge, Justice and with Justice; Knowledge."

A mantra/creed that Athena would find rather fitting - whose symbol was an owl. Athena was the goddess of knowledge/wisdom particularly in the context of war/combat. "And knowing is half the battle." At the very least.

Although… Decorated shields were less for defense, and more came to symbolize a family or order. Soldiers serving a lord often had shields carrying the identity of that nation or specific lord. Noble families or fraternal groups within the military would also keep a decorated shield as an icon of their oath or creed.

Thus, a shield is a natural way to form a patch/badge that has less to do with defense and more to do with the expression of a presence of that creed on the field.
