What?!! How does this even happen? Barring an injury that keeps you from staying in shape, there are no excuses for not being able to PASS such a simple PT test. If I was running the show, I'd give them 30 days to be able to pass and then start getting crazy. As it is, the testing is too easy. Maybe a threat of loss of pay or reduction in rank would get these 2LT' scared straight.
I saw this same issue in a 30 year law enforcement career with a 2000+ officer department. Back in the 80's, we were tested monthly but for a variety of reasons, that went away and the physical fitness & abilities of our officers has circled the drain since. I would bet that at least 1/2 the department couldn't pass the test they were required to pass to get hired. I kind of like to know that my cover unit can get over a 6 foot wall to help me if I'm in a fight.
