The SPM 2.0 was a great mod and it's unfortunate its development was not followed through.You can still use it ( I have an installation with it)but it's not compatible with the current Mission Pack although Mission Pack 1.0c and 2.0 might be compatible.
Funny I don't miss that rangefinder and thermal sights that I use with Steel Beasts. For me using your eyes and MG tracer bursts to estimate distance to the target is more challenging.
