Yeah tanks are great fun. I took part in one of the tank v tank SEA events and it was a blast.
It'll be even more interesting when we get some GREEN tanks. At the moment the Panzer stands out like a sore thumb, but even then it is more than possible to play 'hide & seek' around airbases in them. M16s meanwhile just seem to vanish at times because they blend in to the background much more easily and more much quicker.
ie. spot them from the cupola MG position, just to the gunner position and slew the turret around to where you think they were and now you can't find them anymore =)
Killing fighter hangers at a field from just beyord AAA range is great fun too, I just wish there wasn't the line of smake from the shell pointing right back to you as you're doing this (a cloud of smoke from the gun muzzle would be better). I've even managed to hit a AAA with the first round too, once =)
Anyway, I'm rambling, they're a blast especially in groups when you're using Roger Wilco.
