Antti Pennanen (1903-1989) served as the commander of Detachment Pennanen in Petsamo during the Winter War. In the Continuation War, he was responsible for the same area as the commander of the so-called Men of Lutto of the Separate Detachment Petsamo (Er.Os.P). In the Lapland War, Pennanen and his men saved, among other things, the nationally important industrial facilities in Kemi.
