Earplugs should be introduced into game to add another reality dimension.

Examples:

1. Snipers should always use them. When they dont, they should then experience high tone ear whisle after each shot for random time greater then 30 seconds. When they would use earplugs, they should not be able to hear environmental noises as normally.

2. All Demolitions and explosions should have same effect in some explosion range on all soldiers - AI and Human.
