Agent Kaminsky was a helicopter pilot for S.H.I.E.L.D. assigned to the Cube when he defected to HYDRA and joined John Garrett at the Barbershop Headquarters. When he reported to Garrett, he gave the HYDRA salute, to the embarrassment of Garrett.
When Grant Ward and Garrett had difficulty entering the Fridge owing to the guards' doubts about their loyalty, Kaminsky's S.H.I.E.L.D. Helicopter arrived and began firing on them, so that the guards would believe them and allow them to enter.
