While I've honestly heard only small tidbits about this, I'd assume he means they should be punished appropriately based on military law, but should not be punished inappropriately or more harshly because of the public attention on this particular incident.
Eh, it goes without saying that they're going to be punished much more harshly now than they would have if they didn't post it on the internet. If they'd have just done it, they'd probably get a slap on the wrist and maybe, maybe
a ceremonial reduction in rank (IE: no reduction in pay, no counseling paperwork
) at worst. Maybe even a thousand word essay they'd have to read to the entire company. Making it as public as they did, there's no choice but to punish them for their behavior. Like I said, their careers are over at the minimum.
