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.
The Tech Observation Post is another structure that I personally sought to have it converted to be used in Red Alert 2 from Red Alert 3. In this rendition, it not only retains the wide sight range that gives field commanders an edge in surveillance as it has a sight range of 29 cells, but it also can detect cloaked and submerged adversaries as well. Finally, any artillery pieces placed with in 29 cell-radius of the tower will gain a boosted data link information feed thus increasing its effectiveness, artillery units gain +20% firepower.
If there are any Tech Observation Posts, I'll make it a priority to grab'em! That sort of Early Warning capability and buffing artillery is sure to give me the edge in battle.
