Effects
Invasions: when an enemy launches an invasion of the region, the defending side starts the battle with 1,000,000 damage already on the board for each Defence System the region's owner has there.
Uprisings: both sides benefit. The occupying nation's Defence Systems count for the occupier, and any still owned by the region's original nation count for the rebels.
The bonus is scaled by integrity. A Defence System at 50% integrity only adds 500,000 damage.
Broken (0% integrity) Defence Systems give nothing.
Every battle in a region knocks 5% integrity off all its structures. Repair your Defence Systems between battles to keep their full value.
