I do have some suggestions. The vehicle graphics need to be bigger. I could barely see my, or the enemy vehicles. I could see the Hind helicopters fine, so maybe vehicle graphics should be closer to their size. Also, the infantry symbols should be squads of soldiers like in Steel Panthers not the NATO symbol. It was hard to tell what weapons the Bradleys were firing. I could tell when they fired the 25mm chain gun at the Hinds, but could, or did not see, ITOW's being fired.
I like the terrain graphics and the line of sight graphics. Except for the Hinds, the units should be larger and colored in something other than grey. I really liked the SPMBT colors.
The game has several unit size options. The default option is a realistic 1:1 scale that matches with terrain, and so the units disappear when you zoom out. The other options make the units look bigger when zooming out. I think in the videos the largest option is selected. It should be feasible to add another scale option to make them even bigger.
The Hind is big, because it's big in real life. Perhaps aircraft up-scaling should be moderated.
The missiles are indeed a bit hard to see.
There are many options for customizing the game visuals. In the video, the target lines from the firing unit to the target were turned off. So were the NATO icons. In that old build, when infantry entered a building the unit turned into a NATO icon, even if the icons were turned off. That's different now. Instead, the building roof becomes transparent, and you can see the building interior and other "flavor" objects, and the individual soldiers remain visible all the time.
I need to hear what the artists have to say, but I think the unit colors are based on real camouflage pattern colors.
