OK, Uncle Vintorez hits the Vega!
1) Case: you launch missile without a GSN lock. Provided that no lock was obtained at all, the missile is lost always after the same ~60 km of initial flight, and that irrespective of its initial trajectory (low-alt, for close targets, or hi-alt, for distant targets). What is the reason? At least with hi-alt, the missile should have fuel / kinetic energy to cruise much longer, and drag should not be the issue. Auto-destruction triggered by some "KRO-too-long" stuff, or what?
2) Hpasp, you said once that increasing reflected signal strength while the missile-target distance is decreasing is fully modelled so that the missile can catch the signal in flight even if its strength measured at the radar remains the same (I mean, too low for LOBL). Is it really so? I haven't observed such effect even once, and I am sure there are at least several situations when, if modelled, it should bring a kill.
3) what is the difference between incoming- and receding-target related settings at GSN? Does the missile fired at incoming target with "incoming" GSN setting have a chance to continue track after target turns? In Ashuluk, I managed to kill an incoming target with V<0 setting without any problem. As far as I can remember, in combat scenarios it makes no difference too.
4) Is it possible to see your missile on your Square Pair display? If range screen gives you some idea about group targets, I wonder whether the hit (at least target echo growing for a short while - or blinking - when covered by splinter cloud from a close explosion) should't be visible too? The same with HARM launch from a tracked target (e.g. a speed strip splitting in two, and the latter accelerating before lost from the screen)?
