Alright, time to do my somewhat well known shenanigans again,
So, to the left we have the crews of GuP, from the Soviet, German, US, and British team respectively, today they'll be facing off one of the most sophisticated tanks out there, the M1A2 SEP V2, it's a V2 due to it's CROWS RWS (Remote Weapons Station, remote controlled machine gun basically) on the roof there, each team can bring any tank they'd like from their wide range of tank arsenal, be it the IS-2 for the Soviet team or the Tiger H1 of the German team (the cupola gives it away), now I'll compare their raw performance first, so on the GuP team, their most obvious advantage was their tank's speed and agility, which is akin more to sports cars rather than tanks, this can be useful in navigating terrains and tactical movements such as moving out of cover to fire and then reversing to a safe position, their ammunition also had more post-penetration damage as they had explosive filler inside of them instead of just pure kinetic energy, however that's pretty much where their advantages end, as on the Abrams side, the gun is sorta smaller at 120mm, this calibre is surpassed by some of GuP tanks such as IS-2, KV-2, Jagdtiger, etc, however since the Abrams also had a digital Fire Control System (FCS) and APFSDS rounds to boot, the 120mm gun outperforms even the best tank gun the GuP team has, in terms of accuracy with it's 2km effective firing range and penetration as the M829 can penetrate a Maus from the front at the 2km engagement range, it's protection was even greater as well, with composite armor and depleted uranium inserts on the front side of the tank, giving it an estimated 800mm+ thickness on the turret front, effective against even modern APFSDS let alone APCBC or APCR, and that's pretty much the advantages the Abrams had.
