You have unleashed the chaos of the players knowing too much, too little, and the chaos of both their normal selfs and sleep depreviation on the Marines.

Pity the Marines folks. Pity them.

Become The All Guardsmen Party.

NO!....

Seriously... no. Not again. I already pugged into basically an AGP rogue trader group.... WE SOLD AN ARCHEOTECH BATTLESTATION WITH A MAIN GUN CAPABLE OF DECIMATING AN ORK WAAAGH IN A SINGLE SHOT..... TO TRAZYN THE INFINITE!....

And that was after hauling a frellin norn queen to the cadian sector on behest of the inquisition.

AGP shenanigans are both the best and most terrifying shenanigans.

"We met a dragon!"
"Errata'd."
"I cut steel!"
"Errata'd."
"I leveled up!"
"Errata'd."

the fun part is that none of them noticed the GM has been doing this for a while. Just throwing in wathever they say because he can't think up something in his current state.

Ka-boom.
