| abstract | - The Dělo Automobilní Nabíjené Automaticky (self-propelled auto-loading gun), also known as Samohybná Kanónová Húfnica vzor 77 (ShKH-77) (self-propelled gun howitzer model 77) was designed by Konštrukta Trenčín and built by ZTS Dubnica nad Váhom in the former Czechoslovakia (now Slovakia) as the first wheeled 152 mm self-propelled artillery gun to enter service. It was introduced in the 1970s. It is based on a modified 8x8 Tatra 813 chassis with excellent cross-country mobility. Currently it is in service with the Czech Republic, Libya, Poland, Georgia and Slovakia. Wheeled vehicles have the advantage of being cheaper to build and easier to maintain with greater mobility. Tire pressure can be regulated to allow good mobility off-road and there is power-assisted steering on the front four wheels. It lowers 3 hydraulic stabilizers into the ground prior to firing, and has a roof mounted crane to assist with ammunition loading. The crew of the DANA consists of the driver (operates the hydraulic stabilizers) and commander sitting in the front cabin, the gunner (aims the gun and opens fire) and loader operator (selects the appropriate amount of powder charges) are on the left side of the turret, the ammo handler (sets the shells' primers) is on the right side turret.
