Blackhorse 11th ACR delay vs 117th GMRR advance

[Siddhi]

i've always considered this to be the best armoured scenario in SPMBT, bar none.

quick question though - i've found it a bit dubious that the WP vehicles are all modelled as not having thermals, by the early 1990s (my period) this was definetly not the case anymore, including for the t-72s.

also, i heard a mention back then of supposedly "thermal defeating smoke" (using plastics, or something?) anyone heard of this, at least as a threat perception if not actual WP technology?
