Legal or Illegal mods?

Pigeon_of_War:   Glad you asked this. Different rounds have different sounds and particle effects. An HE round explodes on the tank, HEAT a has a bit of a "sizzle" to it, AP and APCR rounds sound "normal" and have no real sound difference (not a discernible one, at least). This mod is fine because it literally provides zero advantage to the player using it. Say you find out a M103 shot a HEAT round at you. So? With this knowledge in mind, how can you possibly change the outcome of the battle knowing a Heavy tank shot a HEAT round at you? Does that tank have more than one, or was that their last one? Are they loading an AP round if the HEAT round bounced? Who knows?   This is why this mod provides no advantage except your own benefit of knowing what struck you. Everytime I hear about people using it, i file it under the "mostly harmless" category.
