You multiply the corresponding stat by that multiplier (hence the name).
.5 mulitiplied by something is half of that, etc.
| | | tp_heavy: {
| | | | accuracy_multiplier: 0.5f;
| | | | damage_multiplier: 0.5f;
| | | | penetration_multiplier: 1f;
| | | | suppression_multiplier: 0.1f;
This means that the weapon in question (in this case I copied it from a conscript mosin-nagant) shooting at heavy (green) cover will have:
50% accuracy penalty
50% damage penalty
90% suppression penalty (though in the case of every weapon except the MG's and certain other things with suppression, this is irrelevant).
Conversely, the same weapon shooting at

| | | tp_open: {
| | | | accuracy_multiplier: 1.25f;
| | | | damage_multiplier: 1.25f;
| | | | penetration_multiplier: 1f;
| | | | suppression_multiplier: 1f;
| | | };
Open cover (I believe it exists in CoH 2 anyways, such as crossing a road with infantry)
The weapon will then do:
25% extra accuracy
25% extra damage
100% of its original suppression
