So I'm not sure what they all do and what I should use for what kind of targets.

MP-T

HE-T

APFSDS-T

Thanks

MP-T = Multi Purpose Tracer --> infantry/light vehicles

HE-T = High Explosive Tracer --> infantry/light vehicles

APFSDS-T = Armor Piercing Fin Stabilized Discarding Sabot Tracer --> armor

Alright thanks. I knew the APFSDS-T was for armor, but couldn't understand it's meaning. Thanks.
