I believe both the A-10C and F-15E can use both, and they perform similar functions although a promotional video from Lockeed Martin showed some of the features of the Sniper Pod, at least one I remember not being available in the LITENING TGP. This one I think is the one I watched: http://www.youtube.com/watch?v=mTFcmlbn1GQ

Assuming those are accurate, the F-15 should be able to use the LITENING TGP, and I believe the developers will in order to save time, even though I think they use Snipers more often but I'm unsure of that. I'm guessing based on number of videos/pictures I've seen of F-15s. But what made me think of the question is that on one of the screenshots posted earlier, the Launcher wallpaper, you can see it's equipped with the Sniper pod. Needless to say, I'm a bit curious now. :lol:
