In Beta I upped a Tiger2 and whacked the same Gver several times until he upped a p38 to bomb me. What happened was I simply drove under a couple trees (litterally, not a cluster) and he got within D800 of me and had no idea where I was. Although you can see that little dot of a tank without the icons, i smart Gver can position himself so that it is VERY difficult to spot without an icon.
