Very good detailed icons Asuser! I like them very much!
Just a little note... Maybe they will look better still if we try to match the green tone of the tank and the mineroller and the deep wading equipment also (they look a little bit lighter in tone). It is not very important, just an opinion...
But this is an excellent job! Keep it up my friend...
By the way, anything that is more than 148 pixels long will be too big for the game to correctly display, I think... What a good thing would be to add support for double size icons just like in Pacific General (game devs: take note please!). But... as it would be a pity not to be able to field that mineroller tank, here is a quick icon made using Asuser amazing graphic...
a) Reduced to 90% size (only way to squeeze the icon in the 148 pixel "window").
b) "Quick" shadows added.
c) Made the rollers a little darker, to match the tank hull color.
d) Added a M2 .50 cal AA machine gun...
Voilá!

Now, the only thing pending is to make a suitable mask to use with the DCS software...
This special tank unit surely deserves its place in the game, and in my opinion, at least the hedgerow cutter, and the deep wading equipped units, also. They could be useful to visually identify a special unit in the Allied order of battle. Another use can be made of the welded additional armor plated Sherman, to identify a different variant of the tank, as in the game there is only one icon, and this tank was made in a lot of variants...
The log laden and sandbag protected icons can be useful for a Pacific theater mod, as tanks over there were usually modified by troops in the field in that way. In conclusion, with a little imagination we can give use to all those excellent graphics.
