OK, so how about some more Allied stuff? Here's my "wish list"...
1) an updated US M3A1 APC halftrack - could be marked for the Bulge series and/or the DDay series - both are correct
2) a US 105mm howitzer and crew - this weapon served from North Africa to the Elbe in Europe, in the Pacific (both Army and Marines), in Italy, all through Korea, and into VietNam. Quite a long history for one weapon - the Germans didn't manage to produce anything that lastedthat long except the Mauser rifles! Andy could create the molds for the weapon and have different crews and paint jobs as appropriate (yes I am aware that Britains DID do the gun with a WW2 crew - but they sure are NOT K&C quality!)
3) a Sherman M4A1 Duplex Drive for the DDay series. The M4A1 was used by the US forces and a couple of the British units, whereas the British DD's (based on M4A2 and M4A4) were mainly used by Commonwealth units. I have built one in 1/72nd scale - an interesting Sherman variant.
4) another late model Sherman for the Battle of the Bulge series. K&C could take the basic hull of the M4A3 105 howitzer and revise the stowage and change the turret to a 75mm or 76mm - both saw lots of action in the Ardennes
5) As an addendum to the Rangers DDay series, K&C could add some of the Army-Navy combined engineers teams. A four figure set with a demo team, a signalman and maybe a casualty (these outfits took heavy losses). Some of these guys had the Combined Engineer insinia in red on their helmets, and some had the Navy grey stripe on the lower edge of the helmets. Extra insignia detail like this is one of the things K&C figures really shine at and it makes the figures unique.
6) I agree that some more casualties are needed for combat scenes. For those of us who build smaller scenes, maybe casualties could come in two-figure packs? A couple US Battle of the Bulge casualties along with a couple Germans would add to the scene.
7) a revised/updated M5A1 light tank. The early one was OK, but not on par with current K&C tanks. These little tanks equipped one out of four companies in each tank battalion. Could be added to either the DDay series (maybe with wading stacks?) or the Battle of the Bulge series (with heaps of external stowage).
Kind of wordy, but there are some of my suggestions.
