This is not even remotely even. The Wehrmacht would get utterly owned, 1945 German weaponry is a joke compared to what Iraq had.



Tanks



A Konigstiger (ie. the "best"- a joke in terms of mobility and reliability but still) would be lucky to penetrate a T-62, never mind a T-72. We're alsotalking smoothbore high-velocity 115mm guns versus 88mm peashooters. Superior fire control technology would make the Germans look blind by comparison. And at night? The Iraqis would be on a rampage with their far superior night sights.



Infantry



Mechanized Iraqi infantry with lethal anti-tank capability even with their main guns (ie. BMPs etc) versus not even wheel-mobile German infantry (only a small minority of German infantry had even trucks, never mind half-tracks that BMPs make look like a joke ...)



Nevermind AKs, PKMs, RPKs, RPG-7s, SVDs and what not versus a majority of Kar 98Ks, MG42s, MP 40s, Panzerfausts/Schreks and a miniscule number of Stg 44s?



Air Force



Iraq would have total, overwhelming air superiority and by-comparison precise attack/ interdiction capability. The Luftwaffe would be completely annihilated both by Iraqi MiGs and their air defence network- heck, ZSU-23 Shilkas would take the biggest toll. The only losses Iraq would conceivably take are Su-25s, and even then it'd be hardly any.



Artillery



The importance of this can't be overstated. Iraq's got better, longer-ranged firepower across the board (including IIRC South African G5s)- and the command and control fire-control systems to make them accurate as all hell. They also IIRC had counter-fire radars.



I could go on, but this is utter ownage. The Nazis are totally fucked.
