Should say
"Copy German BV 206S as is." (Unit 382)

Update hull and top armour to match Leopard 2A4S. Update speed. Revise FC and RF numbers for the original as well; it has been told to be good enough even against low flying near Mach 1 speed aircrafts.

Should read:
Add LRF to old 1990 one (http://www.military-today.com/artillery/marksman.htm) and revise the FC, for example 110 from the German Gepard which is pretty close to ItPsv 90 Marksman.
