How did the KGB supervise the Soviet Union's border troops?

The KGB was the primary agency responsible for the security of the Soviet Union’s frontiers. Rather than merely supervising these forces from the outside, the KGB directly incorporated the border troops into its organizational structure.123

At its peak, the agency maintained a massive workforce that included approximately 200,000 soldiers serving specifically as Border Guards. By integrating these troops directly into its ranks, the KGB ensured that the protection of the country's borders was a core function of its domestic security and intelligence operations. This arrangement allowed the KGB to function as one of the three pillars of power—alongside the Communist Party and the army—that maintained control over the Soviet state.312
