I had never used too much HE until recently. I didn't use it because switching ammo back and forth was just one more thing I wasn't going to remember to do.
Well like I said it changed a month or two ago. It started by loading HE at the beginning of matches to do more damage per shot on Scout tanks that maraud around for the first minute or two spotting everyone. It works like a charm on thin skinned scouts dealing up to x3 in damage over the AP depending on the gun.
Then I started using it against heavily armored higher tier tanks that I couldn't penetrate, by damaging modules like tracks, view port, copulas and etc. So instead of bouncing round after round of AP at least I could get 40-100 points of damage per shot by damaging modules on these big brutes.
Just in recent weeks I have discovered that if shoot HE against thin skinned TDs I can often one shot them instead of 2-3 AP rounds to a kill. For instance if I am in my Wolverine and encounter another Wolverine I take the time to 'double tap the 3' and one shot him with HE. I assume it will work even better with arty's when I remember to try it out.
So now instead of having zero HE loaded in my tanks, I am now running around 10 per tank as a routine.
Thoughts and experiences with HE?
