Judging by recent trends in international politics and the fact that my country is in a military alliance with Russia, I will be able to personally see and even test (with a help of RPGs) the combat worthiness of Abrams tanks on the frontline at home in the relatively near future. I'll tell you the results once it happens, provided that Bay 12 Forums, the Internet or the USA would exist at that point.
Unless the brave sons of Belarus liberate their land from Batka and his cabal before then.
It's not going to happen in the foreseeable future, unless USA and their NATO buddies decide to follow in their German allies' footsteps and go on a quest to Russia through Belarusian territory under the pretext of liberating the oppressed Russian homosexuals, transsexuals, Siberian natives and oil deposits. Then I'll have to fight the tanks of American "liberators" in my homeland, just like mine and my people's ancestors fought tanks of German "liberators from Stalin's tyranny" more than 70 years ago.Back on topic, I'm still convinced that unless there'll be a border incident that spirals out of control, North Korea will not start a war against the South. We can talk about how KJU is a psycho for a long time, but he won't commit such a suicidal decision as attacking the South - he's not a comic book villain, even though American mass media like to portray him as one in order to justify American military build-up in the region.
Also:
I'd say British (Challengers IIs) German (Leopards), French(Leclercs), South Korean Tanks (K2s) Japanese (Type 10s) are nice opposition for Abrams. Russian tracked coffins with undertrained crews? Don't think so. Same for Chinese copies of Russian coffins with slightly better crews
More modern RPG and ATGM will be a problem, but not T-72 rebranded T-90
Russian T-72s, T-80s and BMPs didn't last very long in 1994-1996. They really were just tracked coffins.
Russians tanks didn't last long during the First Chechen War not because of their inferiority. It happened because of the colossal incompetence of Russian generals that sent an armour column into Grozny without any infantry cover. Without infantry support, Russian tanks, APCs and IFVs were extremely vulnerable to anti-tank RPGs fired from buildings, and Chechen separatists exploited that grave mistake.
Russia also fought other wars since then, such as the Second Chechen War (when they had to attack Grozny again) and the War in South Ossetia (when they had to fight Georgian tanks and infantry in Tskhinvali), and they didn't have as much tanks lost during these conflicts as during the First Chechen War.
