Makes me think about the T54/55 that darn near knocked me out in Baghdad.That’s where they got the firing schedule protocol for the 84mm Gustav. I was an AG for a training cycle and deployment and a gun team leader with one for another training cycle and deployment.
100% it’s contributed to my tinnitus and probably other shit.
You’re only supposed to fire or AG 4 total HE rounds per DAY. At our ranges we’d do upwards of 15-20 a day. You’re not even worried about your ears at that rate. We’d wake up the next day and every muscle in your body would be sore.
One of our gunners got sick from it and probably had a mild concussion/TBI. Holding your nuts and opening your mouth did help a little but it rang your bell pretty hard.
But a 7.5lb rifle shell will do that.
