Well, you can’t really blame them. After all, in the last 200 years there has never been a time that a ship was on fire, anyone had to drag hoses across a deck, or carry a wounded sailor up narrow stairs.
(What else can that idiot in Washington do to weaken our defenses?)
I think people can be a little heavier than the average, and drag a hose while wearing full fire gear just as good as the next guy. Look at the NFL, some of those big fat offensive lineman run sub-5 second 40’s.
