6-year-old Walker Greentree comes from a military family, so he knows a lot about SEALs. He's also a 6-year-old, so he knows a lot about ninjas. When his mom told him and a friend they were playing too loudly, and to be "quiet like a SEAL," Walker protested that ninjas are quieter than SEALs. His friend disagreed, and so they decided to ask the biggest SEAL of them all: Admiral William McRaven, the head of the U.S. Special Operations Command, and the man whom people credit with the raid on Bin Laden.
Luckily, McRaven is also a super nice guy, and he wrote back to Walker. He even included his personal coin in the letter, and was gracious enough not to note that ninjas don't have personal coins. Here's what he said:
To answer your questions: I think ninjas are probably quieter than SEALs, but we are better swimmers, and also better with guns and blowing things up. I can hold my breath for a long time, but I try not to unless I really have to.
Remember, if you want to be a SEAL, you must do two things: listen to your parents and be nice to the other kids. If you do that then you can probably be a SEAL, too.
So there you have it. Final answer: ninjas are quieter than SEALs. Also, I infer, ninjas are badasses who aren't that nice to the other kids.
