Spanish Nationalists during the defense of Oviedo in 1936

The mighty 12-engined Dornier Do X. At the time (1929) it was the largest and heaviest aircraft in the world.

Ansaldo MIAS/MORAS tracked mobile shields. The idea was that a single soldier could walk, then later crouch behind the motorized shield, making it a kind of mobile pillbox. Two prototypes were created, both powered by a 250cc, 5 hp Frera gas engine that allowed for speeds of up to 5 km/h forward or 2.2 km/h reverse. The MIAS and MORAS differed only in armament, with the MIAS being equipped with twin Scotti 6.5 machine guns while the MORAS was equipped with a 45 mm Brixia Model 35 mortar. 1935

The Trubia-Naval was the only tank either side actually mass-produced in the Spanish Civil War, everything else was imported or a prototype. When the Fascists captured the factory, they refused to keep producing it because it was so unreliable. 1937

Spain's first homegrown "tank", the Trubia. As was in vogue at the time, it had two MG turrets stacked on top of each other that aimed independently, so if the top gun jammed you still had the bottom one. A few were built and later thrown into the defense of Oviedo in the Civil War. 1925
