Prince Henry

Colonel Prince Henry Charles Albert David "Harry" Windsor is an officer of the British 22nd SAS Regiment and also is third in line to the throne, behind his older brother, King William V and William's two unnamed children (presumably Prince George and Princess Charlotte). After returning to the regiment "at the reduced rank of Captain", Prince Harry is billeted to HMAS Havoc, where he is captured by the Transition. He has the least bumpy switch of the Multinational Taskforce, due to being a royal. Additionally, he was placed on the Civil List as soon as his identity comes to light. He used that money to fund a tab at the local pub near his Regimental HQ for his officers and men who could run there and back under a certain time.
