When the war turned against them, Japanese artillerymen learned to conceal their positions; their pieces stuck out from hidden mountain tunnels, camouflaged lairs and covered-up foxholes, only opening up with a dreadful barrage when the time was right.
EFFECT:
Until this weapon fires, the enemy suffers from a Very Hard DM to their hit rolls against it or the vehicle it is mounted on.
This effect is army-wide; once one weapon with Shadow Gunnery fires, the effect is nullified for the entire army or fleet.
