My dad has been in the Army basically since he was out of high school and said something similar to me. When weighing the goals and responsibilities of what the army does vs. the navy it seems to make more sense that the Marines should be under the Army's network rather than the Navy's.
Whenever my wife asks me why I never wear pants around the house I simply remind her:
"A lie gets halfway around the world before the truth has a chance to get its pants on.” - Winston Churchill
The truth wears NO pants!
