What great suggestions so far guys!
I agree a German engineer set would be a terrific addition. Figures could have a flamethrower (there were two types - the one in the picture above with the single large gas tank and a later war version with two smaller tanks strapped horizontally), mine detector, wire cutters, and a long handled shovel. Figures could also be laying mines and setting off explosive charges with a detonator (at least one figure should be wearing the special engineer side pouches and backpack used to carry explosives).
I'd also like to see:
-Luftwaffe ground troops on guard duty to guard airplanes, V1 rocket sites etc. They should have a german shepherd guard dog!
-Berlin 1945 nachtjagers (night fighters) with infrared equipped mp-44s and wearing liebermuster camouflage (also an IR Panther tank to support them at some point)!
-More winter 1943 Kharkov SS grenadiers w/ fur lined anoraks (parkas) marching, riding tanks or attacking.
-Later war Whermacht/Heer infantry with splinter and marsh pattern smocks and helmet covers (no one has done a great job of these in 1:30 scale yet), with perhaps a panzershreck (bazooka), throwing grenades etc. Your HB-18 tank riders are a start but I'd like to see attacking troops from this period
-Marching early war (1939-41)/Barbarossa Wehrmacht or SS troops (the latter with early war weapons like an mp-35, erma machine pistol and the Czech ZB-30 machine gun)
-Soviet Naval troops w/ white bandoleers attacking. A common reason given why Russian figures don't sell is their uniforms weren't pretty, but these guys sure were!
-Soviet shock/assault troops (Berlin 1945) wearing breastplate body armor and camo scout suits, wielding captured panzerfausts and pps-43, svt-40. Again, I am not often interested in Soviets but these would be too cool to pass up.
-US infantry in 1945 at Remagen Bridge wearing m43 jackets and pants, firing a recoilless rifle etc.
Other figures of interest to me outside Honor Bound's usual range:
-Commonwealth troops in Normandy and North-west Europe, 1944-45!! Please leave shoulder insignia off so they can be used for both Canadians and British, or ideally give the option to custom paint insignia.
-More Japanese soldiers resting or doing activities in a bunker/command post type situation. I need more guys to complement my Figarti Japanese, and since Letters from Iwo Jima came out there may be a larger market for these than once existed.
Sorry for the long list.
