For a modern Desert Strike check out Cleared Hot on Steam. It's not out yet but it looks promising and it's by a guy who wanted something like Desert Strike. Funnily enough it came up in a similar thread on Reddit a while back and I added it to my wishlist there and then.
49 here and still do it. I also walk along walls if one happens to run along side a path I'm on.
