I don't like using it either...means they are in the sh*t.
One of my "support" Sherman Flails got caught in the open without much support by a T-34/85. The 76mm rounds the Flail has just bounce off it's armour, so hiding was the only option for the moment. I wasn't sure whether it had s/d's or not, and while checking I noticed it had smoke rounds. I knew from earlier battles that my Flails didn't, so that caught my eye. My other type core units ARE getting replenished, so I mis-spoke when I said "my core units" weren't getting any. Thanks for the feedback.
