List of Spanish Civil War weapons of the Republicans

The Spanish Republican forces during the Spanish Civil War primarily acquired their military equipment through the Soviet Union, which provided arms from its own stockpiles as well as weapons obtained from other countries in past conflicts. Their arsenal included a variety of small arms, such as rifles like the Mauser Model 1893, Mosin–Nagant, and Winchester 1873, alongside sidearms like the Astra 400 and Nagant 1895. Machine guns featured prominently, including models like the Hotchkiss M1914, Lewis gun, and Degtyaryov machine gun. Submachine guns, such as the Erma EMP and Thompson, were also utilized.

In terms of artillery, the Republicans employed infantry support guns like the Canon d'Infanterie de 37 modèle 1916 TRP, field artillery including the 76 mm divisional gun M1902 and Skoda houfnice vz 14, and heavy artillery such as the 122 mm howitzer M1910/30. Mountain guns like the Canon de 65 M (montagne) modele 1906 were also part of their arsenal.

Anti-tank capabilities included the 37 mm anti-tank gun M1930 (1-K) and the 45 mm anti-tank gun M1932 (19-K), while anti-aircraft defense relied on the 76 mm air defense gun M1931. The Republicans also made use of armored fighting vehicles, though specific details are referenced elsewhere.

The equipment reflected a mix of Soviet-supplied weapons and purchases from other countries, such as Poland, highlighting the diverse origins of their armaments during the conflict.
