sorry to go off topic but the 3% accuracy increase bulletin is effectively a 3% dps on all units that can use it.
accuracy comes at the end of the dps formula ( rate of fire x damage x accuracy) as a multiplyer and the bulletin applies a x1.03 modifer accuracy to the affected units.
You see, the thing is that virtually NOTHING is described here. You see the durability and repair words, and without any logical reason jump to the worst possible case.
some extra lines from the .ucs file
11084914 Durability is an indicator of item health. Once the durability of an item reaches zero, that item cannot be reused until it has been repaired.
11084915 Repairing an item adds durability to it at the cost of Supply. Once the durability of an item reaches zero, that item cannot be reused until it has been repaired.
11084916 Salvaging an item converts an item’s durability back into supply.
