@Tjoek:
I’m pretty sure there where some other sculpt changes as well, but I don’t know the details by heart.
The German artillery piece is now a genuine field artillery piece (the 105mm LeFH 18 howitzer), while the 88mm FLAK is now correctly being used as an AAA piece.
ANZAC and Italy now have a full set of nation-unique sculpts. ANZAC also gets its own infantry sculpt, which it lacked in the 1st edition; Italy already had one, and retains it.
All the players powers (except for China, which only has infantry) now have an AAA sculpt; all but France have a nation-unique one.
The US, ANZAC, Germany, Japan and Italy now all have a 14-unit sculpt array (infantry + 13 equipment types) of fully nation-unique sculpts. The UK lacks a nation-unique naval transport and the USSR lacks a nation-unique aircraft carrier, but they can be obtained from A&A 1941, which fills both gaps. A&A 1941 can also conveniently provide China with a P-40 Warhawk fighter, which is the actual aircraft used by the Flying Tigers.
France continues to have a nation-unique infantry sculpt, and its equipment pieces continue to be clones of the Soviet sculpts; however, the Soviet sculpt upgrades in the 2nd editon are reflected in France’s 2nd edition sculpts.
