If SB2's IR/NV system works anything like SB1's, it should be quite easy - SB1
uses a different skin for vehicles when in NV mode, so the CIPs would just have to be painted on
the appropriate places. Of course if SB2 uses a more sophisticated system for IR/NV, it would
make things a bit harder!
I only found out about CIPs a few months ago, when I made some for the semi-scratchbuilt
1/24 Bradley model I was working on.
