Funny thing.... I have an airsoft tank as well, one of the Hen Long M-41's. It's a little larger than the T-72. I actually managed to shoot a bird in the yard one day with it. I also shot my last cat, sometimes point blank. He never even batted an eye. I don't think he even felt it, thru his fur. Of course it wasn't exactally the strongest airsoft gun ever, but still..
