Level 5, Head of Munitions, responsible for Section’s arsenal. Originally recruited in 1965 as a field operative. Spent 10 years in Spec Ops. After a mission where the rest of his team is killed, Walter decides to move into a department of Section with a better "survival" rate!  Current duties include weapons inventory and repair, explosives, and new weapons development. All weapons and equipment are locked up and must be distributed by Walter. When a team is in "prep" they are usually in Munitions collecting their weapons, gear and panels. Prior to a mission and after a briefing is concluded, Birkoff downloads all pertinent information, mission parameters and/or changes and gives them to Walter. Walter then issues the panels during prep. After a mission is completed all weapons, gear and panels are once again returned to Walter, logged in, and accounted for on inventory. Munitions’ inventory is closely monitored by Madeline and Operations. Any anomalies are Walter’s responsibility. Walter has been in Section for over 30 years and remembers when Operations was recruited. From conversations Walter has had with Madeline it would appear Section’s atmosphere is quite different from its inception – the focus of protecting innocents has been lost with Ops quest for increasing power. Walter’s last name is not known. Married once to a fellow operative named Belinda. The marriage did not last more than a few days as Belinda was sent on an abeyance mission. Operations feels he owes Walter something due to her death. Walter created "the 5% club". He believes 95% of the recruits have their souls sucked out of them within the first year. . .but Section doesn’t get to everybody, thus the 5% club. Considers Birkoff his best friend, calls Nikita "Sugar", and has helped Michael and Nikita on several occasions. Although betrayed by Nikita in S4 finale and sent to The Farm for violations against the Charter, he returns to Section in S5 at her request. At the end of S5 he remains in Section as Head of Munitions.
