I have found some interesting videos at http://www.danskpanser.dk/Panser/film.htm. Especially this one from a shooting exercise - Probably Leopard 1 against Centurion, M-10 and maybe even Sherman targets : http://www.danskpanser.dk/Film/JDRkontrolskydning2003.WMV
That shooting exercise video was interesting. A tank firing shells into a pile of something without doing much. And the language. Probably german, since Leopard tanks are German.
It probably didn't do much because chances are it's practice ammo they were using. The web address is Danish, so the language most likely is too. Still, very interesting.
It is danish and it is Leopard 1A5 (which is no longer in use, now using Leopard 2A5) from 3. tankcompany/III. battalion/Jyske Dragon Regiment (note the 3/III/JDR in the top corner of the video) and they do use training ammo which dont do anything else then to mark where the round hit the target (it dont blow up the target or something like that)
