• building = /6
• green = /4
• yellow = /2
• moving = x2
• veterancy = +5% per star

Examples:

• infantry (normal optics) vs infantry (good stealth, green cover) = 400m/4 = 100m
• recon (very high optics) vs AT gun (medium stealth, green cover) = 2400m/4 = 600m
• tank (very low optics) vs AT infantry (very good stealth, no cover, moving) = 150m*2 = 300m
