The YT-3 Crocodile is a 3rd Generation Main Battle Tank produced in Inyursta. Designed to replace Inyursta's aging fleet of Cold War legacy tanks, the YT-3 would go on to see widespread in a number of combat zones. Key features of the YT-3 include a modern smoothbore cannon, composite armor and advanced optical targeting systems.

Design Features

Armament

The primary armament of the YT-3 Crocodile is the Entengo 120 "Marauder", a 120mm smoothbore cannon. A locally-produced clone of the Rheinmetall_Rh-120, the Crocodile typically uses the L/44 length cannon, though a small number of YT-3M3 units use the L/55 length and the YT-3M4 in use with the Inyurstan Marine Corps uses a shortened L/39 length to better fit into landing craft. A number of projectiles can be carried, including the N50A Armor-Piercing Fin-Stabilized Discarding Sabot (APFSDS) series, the N49N2 High-Explosive Squash Head (HESH), N62E1 SONIC guided anti-tank shell, and most NATO 120mm ammunition such as the M829. 42 rounds of ammunition are stored below the turret.

Secondary armament includes a coaxial 25mm autocannon, the RK-25 "Shockwave", for engaging lightly armored vehicles and infantry positions. Typically 100 rounds of 25mm are carried, though additional ammo is often stored externally. A topside 14.5mm heavy machine is mounted atop the turret. Block I models had this gun manned by the commander's position; however, following the Block II upgrade and production standard from 2010-2016 all manned guns were replaced with remote weapons systems (RWS) controlled from the safety of inside the tank while allowing enhanced imaging options to aim the gun.
