crew cabin seats both the driver/mechanic and vehicle commander. The armoured turret is installed on a traversable mount adapted to the Tatra 815 wheeled chassis (8x8) and is divided into two halves, divided by the howitzer's recoil mechanism and a pathway for the reciprocating action during firing. The left half of the turret is occupied by the gunner and first loader and houses the various fire control optics, electro-mechanical gun laying controls, the automatic propellant charge feeding device, and an auxiliary ammunition magazine. The right side of the turret contains a mechanized projectile delivery system which is operated by a second loader at this position. The DANA's primary weapon is a 152 mm howitzer with a monolithic barrel (with a fixed rifling pitch) equipped with one expansion chamber. The howitzer has a semi-automatic, vertically-sliding-wedge-type breech which opens to the left side. The recoil assembly consists of a hydraulic buffer, two pneumatic return cylinders and a controlling plunger which governs the displacement of the buffering system. The gun laying is carried out by an electro-hydraulic drive system or an emergency manual control. DANA's unique feature is that its autoloader is able to load a shell and a cartridge in any elevation of the barrel. As there is no gyroscopic or similar system for independent, automated and autonomous gun laying in the DANA, the gunner of howitzer uses a ZZ-73 panoramic telescope with a PG1-M-D collimator for indirect gun laying. This sight has a horizontal scale used to set the appropriate horizontal laying via aiming at reference points. This means that the DANA is not an autonomous system there needs to be an additional device to assist in gun laying (in fact, the firing positions of such artillery systems are usually prepared before the guns are positioned there). For direct fire engagements, the gunner uses an OP5-38-D telescopic sight. Ammunition As of 2014, there are three main shell types used by Czech Army: 152-EOF, which means "high-explosive" with a maximum range of 152-EOFd, which means "high-explosive long-range" with a maximum range of 152-EPrSv, which means "high-explosive anti-tank" used for direct-fire at armored targets General characteristics Length: Width: 2.8 m (9 ft) Height: 2.6 m (8.53 ft) Weight: 23,000 kg (50,706 lbs) Performance: Maximum Road Speed: 80 km/h (50 mph) Range: 600 km (373 mi) Rate of Fire: 3 rpm for 30 minutes Maximum Gun Range: 28 km (17 mi) Fording: 1.4 m
