I probably sound like a broken record every year with these ideas, but here they go:
--Captured vehicles being pressed into service against their former owners (jeeps, schwimmwagens, halftracks...)
----SdKfz 250/9 (with a 20mm gun turret) and/or Sdkfz 250/3 (radio/commander's vehicle)
----SdKfz 251/1 II -"Stuka zu Fuss"
--What I like to call "out of action add-ons" (tank crew loading shells/ammo boxes, greasing drive wheels, welding, breaking track...) and regular soldiers cleaning rifles and machineguns, dubbing boots and other maintenance tasks.
--"In action add-ons" (full or half body figures molded manning machineguns on vehicles (think two figures for "FURY": one full bodied manning the .50 cal, and one half bodied in the commander's hatch manning the .30)
--Germans wearing camouflage uniforms and driving camouflaged vehicles....Gray has its place, but for the most part is boring
--Since Andy's making a pivot to the Pacific, I'd like to see a small patrol of US Army "Alamo Scouts" in camouflage uniforms doing reconnaissance against Japanese positions
