It's the culture....
In my limited time working with the USN and for a USN Captain, the phrase I grew to dislike was:
"Navy can do!!" - even when it was apparent that they couldn't, and in several cases, shouldn't. It led us down blind alleys and into situations we didn't need to be in.
Almost on a par, was the phrase "Of course I never take my leave. Anyone who can take two weeks leave hasn't really got a job!" Yeah right.
You can almost hear the guy saying "Rest is for wimps, I can hack it!"
Bosses like that we can all do without.
