Why do we have an Army or a Marine Corps?
That seems like a silly question. The answer appears so obvious that it doesn’t deserve a response.
There are those, however, who are stumped when asked.
These are folks who have little to no understanding of military issues and have trouble grasping basic ideas, such as the purpose of having a standing armed force to protect the nation and its interests.
These are the same people who are pushing to integrate women into combat arms.
