5. 10th Special Forces Group (USA, Cold War Europe)

The 10th Special Forces Group (10th SFG) emerged in the early Cold War, with a mission to operate behind enemy lines across Europe. Tasked with training and supporting resistance movements in case of Soviet aggression, the unit played a vital—yet often unheralded—role in NATO’s defense strategy. While less famous than the Navy SEALs, the 10th SFG’s expertise in unconventional warfare and alliance-building helped shape the future of American and European special operations.
