Thermal imaging

[Marcello]

Thermal sights can see throught a large variety of battlefield oscurants including conventional smoke, sandstorms etc.This is true now as it was in the 90's and the 80's. It was one of the most important advantages western tanks had over their eastern couterparts during the late Cold War and its importance was shown in several egagements during the Gulf War.
I suppose that in theory thick smoke should block LRFs but in practice I never heard it to be mentioned as an issue during GW1.
