My assertion was Iskander is one of Russias best weapons, arguably more effective than Kalibr per rate of fire and very likely equivalent to ATACMS, or possibly better in terms of capabilities given it's a larger munition. > There seems to be a wide gap in capability between the two scenario This is entirely premised on Russian air defense being equal in high value areas vs Ballistic missiles (which is easily the hardest test, even for the US). Patriot systems were tested many times IRL against SCUD missiles during Desert storm and more recently vs Iran, plus general skill available in US R&D/military, while Russia never tested their S-400 systems in (real) combat and is notorious for poor maintenance/training. Unless you equalize these 2 things it's a moot point. RU missile teams have had plenty of press about improving their operational effectiveness in the last year. AA has not. Additionally, these systems aren't that sophisticated, it's GPS+inertial navigation+maneuvering+maybe some limited anti-EW. The rest is intelligence, EW, operators, etc. ATACMS was designed in the mid 1980s after all...
