Thermal imaging

"And indeed laser beam is so coherent, that it´ll pierce smoke easily. Try it home with a laserpointer-pen and some smoke from, say, a smoke generator, that everyone has under their bed."

Just because the laser does not dissipate after three meters this does not mean it won't be an issue at 3000. AFAIK bad weather is considered a problem for LGBs. But perhaps it was not an issue at engagement ranges.

"However radar doesn´t help shooting at land targets, as you may have guessed already."

I might be wrong but IIRC the soviets had deployed radar sights for the MT-12 antitank guns. Take this information with a pinch of salt though.
