Sneak attack (Fearless Blue)

just before someone took over my Fearless blue country I tried the sneak attack
the only weapon it allowed was 2 cruise missile batteries
all it did was destroy the 2 batteries and shoot up some missiles both ways
Is that the only weapon available

I've never done a sneak attack, but I suppose so.

It'd make sense if special forces worked as well, or even land forces if you had military transport airplanes I suppose (if they can land without airbases).
