Colonel Kane is a lifelong soldier and a highly-decorated Colonel, and had been a field officer with USSOCOM for most of his career, leading numerous tactical operations across the globe as part of the 3rd Special Forces Group. His wife Gabi Kane was a Captain with the 525th Battlefield Surveillance Brigade. Both Kanes worked extensively with military intelligence services.
Jacob and Gabi had identical twin daughters, Kate and Beth, and the family frequently moved due to the nature of Jacob and Gabi's work. Jacob was often away from home, since his duties included intervention in various international military crises.
The Kane family eventually moved from Fort Bragg, North Carolina to Brussels, Belgium, since the parents were now serving in NATO. However, the family was soon torn apart due to a terrorist attack. Gabi took her daughters out to celebrate their twelfth birthday, and they were kidnapped by heavily armed men. Military intelligence eventually located the hostages, and Jacob was put in charge of the tactical unit sent to rescue them. However, they were too late, as his wife had been executed and his daughter Elizabeth was believed to be dead. He rescued Kate himself, but she was traumatized by the sight of her dead mother and sister.
Colonel Kane plays an important role in his daughter's Batwoman operations. He provides her a one-man command, control, and communication center. They stay in constant radio link, with the elder Kane being able to run searches, provide advice, and generally work in the background using his considerable knowledge, contacts and experience. Colonel Kane primarily uses his connections and his intelligence-gathering and management skills. He has access to numerous databases that are normally only accessible to military and law enforcement personnel to provide intel to his daughter.
