For my taste the Italian and Russian mechanized (or better “motorizedâ€) infantry as well as the Priest are ugly!
Since I already own A&A Classic (1984), Pacific (2000), Europe (1999) & 1942 (1st Ed.), I’ve never bought A&A1940. I simply got myself the board, some miniatures for ANZAC & Italy and some more cruisers. There was definitely no need for more US, UK, Jap, Ger & Rs units. – Especially no need for more useless Russian ships! :-)
Concerning a historical perspective, the only real fully motorized armies were those of the US and the UK. So our gaming group is pleased with the idea that the small portion of motorized units are part of the tanks.
The development of „mechanized infantry“ via R&D enables you to accompany each tank with one regular infantry (this represents a greater portion of mech. or mot. units in comparison to your regular inf.)
