Sean Hamilton-Mitsotakis was a Beowulfan citizen and an officer of the Biological Survey Corps.
Holding the rank of Colonel in the mid-19th Century PD, he served as the commanding officer of the Special Actions Group, assigning assassination targets and planning the neccessary operations.
When Captain Jacques Benton-Ramirez y Chou informed him that his twin sister Allison had been abducted by Mesan mercenaries, Hamilton-Mitsotakis decided to launch a rescue operation. He argued that the Prescott-Chatwell law's prohibition of BSC actions on Beowulf itself was irrelevant in this case because the Mesan operation was a direct attack on the Corps itself. (HHA6.3: BATB)
