"Also important to remember is that in the Leopard 2, dynamic lead is to be used only if the target itself is moving. Apparent movement due to your own tank driving with the resulting parallax shift doesn't count. "
I remember hearing, and I haven't been able to find any references to this from any other source, but instructing officer told me that certain crews in other armies (and I think he was talking about Swedes) would use ductape to push down the dynamic lead button in their Leo 2, to have it active at all times. He said they can still hit static targets when its pushed down, just by keeping the reticle in the middle (thus not applying a lead for the FCS).
Now it could be that all he said is total bullshit just to make me confused or that he had missunderstood something. Or maybe Swedish gunners are just ex-surgeons with very very steady hand. Or maybe the FCS of Stridsvagn 122 differs in this regard...
