There is a difference, the late physicist and pop philosopher Richard Feynman used to say, "between knowing the name of something and knowing something." The military puts a lot of emphasis on the names of things, especially its operations and exercises — from Salty Hammer to Viking Snatch. Who else puts so much thought into a name, only to come up with such silly monikers? Your friendly cannabinoid salesmen. And if you plan on going far in either career field, you'd better know the differences.
