Together we are stronger, our voices louder, and the synergy of our actions more powerful. Together we can prevail on the Navy to put commonsense safeguards in place, like requiring its ships to avoid the most sensitive marine mammal habitats and to stop their training exercises during peak migrations.
In the Marine Corps, your buddy is not only your classmate or fellow officer, but he is also the Marine under your command. If you don't prepare yourself to properly train him, lead him, and support him on the battlefield, then you're going to let him down. That is unforgivable in the Marine Corps.
My definition, the definition that I've always believed in, is that esprit de corps means love for one's own military legion - in my case, the United States Marine Corps. It means more than self-preservation, religion, or patriotism. I've also learned that this loyalty to one's corps travels both ways: up and down.
