Petrov
Señor Pinga is a Petrov HS-100 that Zenia Zayas painted to look like a pig and fitted with loudspeakers. It is a Libertad tank you unlock through Yaran Stories in Madrugada.
Same as a standard HS-100: bulletproof, strong cannon and good against helicopters. The look and the speakers are the bonus.
Finish the two-part Yaran Story Stealing Thunder in Madrugada, then complete Heavy Metal. The tank is then added to your list at vehicle pickup points.
Cargo Truck
Cargo trucks are the FND's big 1967 Yuri 151 military trucks, used to haul troops, supplies and prisoners around Yara. They are slow and tough, and stealing one is a common way to hit the regime's supply lines.
Petrov HS-100
The Petrov HS-100 is the FND's main battle tank, armed with a 105 mm cannon and two machine guns. It is the first drivable tank in the Far Cry series, and stealing one turns any fight in your favor.
Petrov HS-100 "Karlito"
Karlito is the Legends of 67's old Petrov HS-100, rebuilt during the 1967 revolution with a shorter cannon and a turret flamethrower. You recover it in El Este and it becomes yours after the operation Harpoon.
Petrov HS-100 B
The Petrov HS-100 B is the black-painted version of the FND's main battle tank. It is otherwise the same as the base HS-100, including the weak spot at the back.
