A fan for Real life Military equipment ? then this is your mod ! it is a Red Alert 2: Yuri's Revenge mod that basically imports a lot of RL military hardware from the cold war era in the 60's to the late 2000's while maintaining a lot RA2 aspects like prism, tesla tech and etc. Also, It expands on the original RA2 armor system thanks to ARES in which it creates more roles to create numerous units effectively expanding the complexity of handling an army making it necessary to use mixed arms to counter the various unit types. Also, do note that each country will have some twists in their military equipment that will be more or less similar to their respective RL counterparts. In short: it is a relative to reality fun mod but "a fun mod" is conservative statement.
Allied and Soviet navies will follow a similar path to RA1 albeit a modified one. Allies will place more emphasis on its non-submerged naval vessels. On the other hand, the Soviet will lean more the submarines to complement its standard naval vessels.
The Allies will mostly have 1-2 type of submarines and the Soviets will have at least 3-4. Both will be able to build shipyards and sub pens to build the relevant units.
The Akukla-class submarine is your standard and reliable vessel killer it work in similar in that of a destroyer.
It has 2 modes, its first mode is that it uses both of its torpedos and Kalibar cruise missiles, whilst submerged the former can be lunched in salvoes of 2 and the latter will make the sub emerge so it can attack land based targets of which it is specifically made to deal with defenses whilst being also decent against standard structures.
The 2nd mode of the akula is that it would always be emerged to use its main weapon. The weapon range is doubled but also slavo number is halved when launching torpedos.
