10. Swiss Mercenaries (Renaissance Europe)
Swiss mercenaries were renowned for their formidable pike formations, known as “pike squares,” which were instrumental in their success across Europe. These formations, consisting of disciplined soldiers armed with long steel-tipped pikes, allowed them to effectively counter cavalry charges and break enemy lines. Their expertise in mountainous, snowy terrains further enhanced their reputation, making them highly sought after as mercenaries during the Renaissance period (warhistory.org).
