There exists today shotgun style ammo for MBTs for anti personnel applications.
I would simply like this to be added to arma. It seems like a relatively easy thing to do code wise. However, I also realise producing 300-500 pellets all with bullet penetration calculations could be difficult to process but given the number of AI I can have shooting at full auto it doesn't seem like it would be that much of an impact on performance.
It would be great for clearing buildings with tanks.
