My group included a Corporal Mallear (Sergeant), Trooper Zel (Heavy Gunner), Trooper Natialia(Ratling)
So my group has managed to make it to the supply depot and after a few days in the medicium by Corporal Mallear for previous injuries. The group got to enter into "The Hole" for some recreation. The corporal found an illegal game of Tarot, and invited himself into the game. After winning the first game, the other Sergeant at the table called the Corporal out. And bet his entire stack of funds in a winner take all match. After the first three cards, the corporal noticed that the Sergeant was using slight of hand to deal cards from the bottom of the deck to the corporal. The corporal called the sergeant out about this and the deck was handed to the ratling to deal out the rest of the hand. After the corporal won the hand, the Sergeant was getting really angry with the corporal and with his raised voice brought the attention of a commissar. So instead of hanging back and letting the commissar handle the angry sergeant, the corporal stood up and accused the Sergeant of Blasphemy against the Emperor. With the great deceive roll the that ratling had was able to convince the commissar. That the corporal was telling the truth, this caused the commissar to take the Sergeant out of the Hole, and he was burned at the stake the next morning.
This was one of the funniest moments I have seen in a 40k game. I asked the corporal why he told the commissar that, he told me that he panicked and thought the commissar was going to kill his character for gambling.
