I'm a bit at a loss for what to do when my opponent brings out an ISU or an Elephant. I know they're expensive but you can't keep people from fuel all game and sometimes they do arrive.
What can you really do apart from getting your own super TD and shooting back?
Most of the time they're sitting so far back that you're not getting close with infantry(elephant) or doing so would be suicide (ISU).
Any good tips to share?
I was thinking bombing or artillery strikes, but do they really have the firepower to make a dent?
Most important thing is to chose time and place for battle. Heavy tank destroyers (Elephant) are usually very slow and take a lot of Pop Cap.
This means you should be able to play some 'guerialla tactics' hit and run, use line of sight and try to weaken the enemy. Make Elephant chase you around the map, Force it to move around. Don't have a standoff with it.
Concentrate more on infantry and make opponent bleed manpower/resources.
Remember Elephant is terrible vs infantry.
Thats if you are playing 1v1, if you are more into team games. I don't really have solution other than: better hope someone has Heavy Soviet Howitzer and is willing to help you out....
P.S. Bombing and Arty are most effective counters for Elephant...........
