The instilations have an unlimmited LOS and bullet reach. This allows any person who likes to get on any of these and pin down and very, very easily destroy any tank on the entire map from that instilations point of view. Tanks, on the other hand, have a limited range and line of sight. Tanks travel on the map going about their day and they are suddenly struck by a mighty blow that they can not see, as they lack unlimmited LOS. The shots are endless and unrelenting, chasing the tank untill he is ethire destroyed or hidding behind something that breaks the LOS, were he will ethire sit for ever or recall the tank. He cant do anything else because he cant see what is killing him from litterally the other side of the map. So the tanker recalls his tank and geusses were the railgun is and trys to kill it. The process begins again untill he lost too many tanks or is secessful. Btw, this is happeneing durring a battle, other ppl have AV too! BtwBtw, this is most imfamously abused on the bridge map

you are asking someone to be omnicient of everything going on at once and expecting someone to know the status of invisible turrents. do you know if that invisible turrent is alive or destroyed?
