Well, I'm looking a few right now, I've got the stats but I'm using existing graphics and would like new ones so it's unique:
An early hunter/trapper - Ancient Era (Recon upgrade unit, foot unit that melees with spears and has no shield - right now using Spearman model with Scout icon game statistic follow in spoiler tags if needed).
Mounted Scouts - Medieval Era (Recon upgrade unit, mounted model without horse resourse requirement, uses melee, either spear or shortsword without shields would be fine - right now using Horseman model with Scout icon)
Explorer - Renaissance Era (Recon upgrade unit, mounted model - again without horse req - that uses melee, preferably sabers, and perhaps carries a spyglass when not fighting; currently using Conquistador model with Scout icon - Gunpowder, I know but that isn't a tech requirement for the unit so I'd rather get away from it, just like the Cortez look)
Forward Observer - Industrial Era (Recon upgrade unit, would like units riding pre-WWI motorcycles or early jeeps with passenger having binoculars, gunpowder unit that fights with late 19th century firearms, sidearms preferred over rifles; currently using Great War Infantry model with Scout icon - later era, I'm aware but I've had to make do so far)
Force Recon - Atomic Era (Recon upgrade unit, either riding WWII style jeeps or foot units - would like something akin to the Marine Recon ala Heartbreak Ridge - gunpowder unit that fights with modern rifles; currently using Marine model with Scout icon - could stand for same models if in jeeps otherwise something to set them apart from regular marines)
Combat Engineer - Information Era (Late game worker with minor combat capabilities intended for hazardous or hard to reach areas, foot unit, would like something akin to late era workers but in military uniforms, gunpowder unit that fights with modern sidearms; currently using Marine model with Worker icon - unit has access to paradrop and is intended to repair/construct frontline improvements or access areas regular workers cannot)
Danrell's got some nice models that will fill some of my other desires for now (some bridge units for overly long upgrade paths Frigate/Lancer specifically).
