Intrusive Leadership

USS Hartford (SSN 768) was in the news for something good today. They were commended by the Navy for going 1000 days without a DUI. Excerpts:
Prairie Grove, Ark. native Cmdr. Robert Dunn, Hartford's commanding officer, accepted the commendation on behalf of the Los Angeles class attack submarine.
"Although you're giving this to me as the commanding officer, the intrusive peer leadership of the hard-working Sailors makes this possible," said Dunn.
The crew also received a personal message from Submarine Force Commander Vice Adm. John J. Donnelly, calling Hartford "a prime example for the submarine force on how focused effort and deckplate leadership can curb reckless behavior and poor decision making."
"I recognize the fight to prevent DUIs is one of many tasks you undertake which requires constant, intrusive leadership. Hartford's accomplishments in this area are a testament to the crew's professionalism and dedication," wrote Donnelly.
What do you think of the value of "intrusive leadership"? Is it the right philosophy for the unique crew composition of submarines?
