The term, "Los Tiznaos" means 'The Grey Ones' in Spanish. The name was used by the population at large when referring to the AFV's of the Spanish Civil War. Here the name "El Tiznao" it is used here to refer to the various armoured trucks, both manufactured and makeshift, the Republicans used throughout the war. One of the factories that produced these vehicles was the largest locomotive and engineering factory in Spain -- 'La Maquinista Terreste y Maritima' (MTM), of Barcelona.*

They produced many vehicles, but some of the more famous are noted in this text.*
*
The Camion Blindado 'Durruti' were built shortly after the uprising. The Durruti was crudely armoured in steel sheeting. The vehicles saw action primarily with the Durruti Column.*
*
Also produced was the Vulcan Mark II. Work began on the Vulcan in November, 1936.  The basis for the the chassis on these heavy armoured vehicles were Chevrolet SD trucks. Only two Vulcans were constructed. The Vulcan Mark 2 was not completed until early in 1937, and saw use in the Teruel region.*

"The Louse," El Piojo, was a single-decker Paris Bus.  This was a huge vehicle. It survived in its original condition until May 1937 when a German Pilot flying with the 'Condor Legion' caught the truck and put it out of use. German Ace Pilot Schultz's speciality was strafing enemy columns, and he referred to this action as 'Louse Hunting'. The "Louse" was found on the road between Durango and Ochandiano and the Nationalists managed to rebuild the vehicle later, albeit in a modified form.*
*
The "Mobile Pillbox" was another monstrosity.  Very vague information surrounds this armoured truck. This huge vehicle was the brainchild of the CNT/FAI and UGT Militia.  It was known to have been in use with Vulcano and Durruti MTM vehicles in an Anarchist column, nothing more is known about it.*

The Durruti type of armoured truck is modelled here in the game to represent all the various armoured trucks used by the Republicans throughout the war.*
