Some corrections for oob 34 italy:
unit 015 and 016 M47 Patton: available till mid 1989 (average date);
unit 027 B-1 Centauro "vanilla" entered service in 1991, late in the year. 100 produced before new uparmored version was developed (further 300 delivered till 1996). These first 100 vehicles were put out of service in 2004.
unit 025 C-1 Ariete in service from March 1998. End deliveries of 200 vehicles in July 2001.
Up-powered Ariete is still a dream as for today
;
EF-2000 in Air-to-Surface role is still a wish, and so will be for some years (for every Nation tha have it).
The game depicts two types of mechanized infantry: Bersaglieri and mechanized on wheeled APC. This was not the case: all mechanized infantry was organized as the Bersaglieri, with the latter being somewhat elite (more or less, maybe less, as Guards and Gurkhas in respect to basic infantry in the British Army); so all on VCC-1/2 or M113. No wheeled mech infantry ever existed: only cavalry recon groups experimented the vehicles for some time in early '80s. FIAT 6614/6616 were mainly used by Carabinieri and Police forces.
Sources are from some italian sites and forums, and publications I have, but something can be found in english language I think.
I hope this can help.
