- “We knew Master Chief was in the fight. He gave us hope.”
It should be noted that his testimony is not entirely reliable. While it is possible that Czernek fought in New Mombasa after its destruction, John-117's intervention in the battle is fabricated, possibly by ONI in order to cover up the true circumstances surrounding John's disappearance and the end of the war from general public.
During his retirement, Czernek was interviewed about his experience during the Second Battle of Mombasa at the Museum of Humanity. The shots shown during the interview broadcast are of Czernek viewing a commemorative diorama of the battle and of the diorama itself. At the beginning of the interview, Czernek is shown slowly approaching the diorama with a visible prosthetic in place for an amputated right leg. His leg is assumed to have been lost during the battle.
According to Czernek, during the Second Battle of Mombasa, he and his unit began to run low on ammo while fighting the Covenant. He and his unit had to scavenge the ground for any available weapons and ammunition as they waited for support to arrive. Czernek continued fighting with an M41 LAAG on the back of an overturned Warthog when John-117 arrived with a primed grenade in his hand.
- In the Believe diorama, Czernek is possibly the Marine seen on a damaged Warthog several meters from the Hunter from the beginning, since he described himself being in that location during the interview.
- Due to his name and strong accent, it can be assumed Czernek is of Eastern European descent.
