House of Horrors
Both Area A (Prince William Forest Park) and Area B (Catoctin Mountain Park) had a House of Horrors or 'pistol house.' In the dead of night recruits would be awakened to complete real life instinctive firing exercises.
One of the more complicated military maneuvers is a frontal assault on a fixed position. Here, recruits attempt to fire upon two foreign tanks.
