The **Polish Military**, formally known as the Polish Armed Forces (Siły Zbrojne Rzeczypospolitej Polskiej), is a comprehensive defense organization tasked with safeguarding Poland’s sovereignty and contributing to NATO collective security. It consists of five main branches: the Land Forces, Air Force, Navy, Special Forces, and Territorial Defence Force, supported by military infrastructure and logistics units[1][2][4]. Established in 1918 and modernized significantly since 1990, the Polish Military has a rich history rooted in national defense and resilience. Recently, Poland has embarked on an ambitious expansion and modernization program, driven by geopolitical tensions in Eastern Europe and the ongoing war in neighboring Ukraine. The force has more than doubled in size since 2014, reaching approximately 216,000 active personnel in 2025, making it the third largest military in NATO after the United States and Turkey[2][5]. Key achievements include the rapid growth of personnel and the acquisition of advanced military hardware. Poland is investing heavily to reach a defense budget of 4.7% of GDP, the highest among NATO members, equating to about $35 billion in 2025. This funding supports modernization across all branches, including a planned fleet of around 1,100 main battle tanks—combining domestic PT-91 Twardy models with German Leopard 2A5, U.S. Abrams, and South Korean K2 tanks—and advanced artillery, air defense systems, and mechanized infantry units[1][5]. Current initiatives focus on expanding the Land Forces with new divisions such as the 8th Infantry Division, enhancing Territorial Defence with 20 brigades, and improving interoperability with NATO forces through updated command and control systems. Poland also hosts approximately 16,000 allied troops, underscoring its strategic role in European defense[3][5]. Notably, Poland’s military-industrial base is growing, producing indigenous equipmen
