William McRaven, the head of the elite U.S. Special Operations Command, responded to a question from a 6-year-old boy on ninjas.
Walker Greentree, 6, wrote a question to McRaven–who himself is a SEAL–asking him if Navy SEALs are quieter than ninjas, reported Business Insider.
“When I grow up, I want to be SEAL too. But, can you tell me who is quieter – SEALS or ninjas!”
McRaven sent a response.
“I think ninjas are probably quieter than SEALs, but we are better swimmers, and also better with guns and blowing things up,” he wrote.
The question and answer was posted on Blue Star Families, a military nonprofit.
The curiosity was sparked when his mother, Vivian Greentree, told William to be “quiet like a SEAL.” One of his friends then responded that “ninjas are quieter than SEALS.”
