Battleship barrages in World War II were massive naval bombardments utilized primarily for shore-to-sea attacks to soften Japanese defenses in the Pacific and Axis positions in Europe, often preceding amphibious landings. These barrages, characterized by the 16-inch guns of Iowa-class battleships and others
Should Japanese maps have Battleship barrages instead of arty?
Probably for those game modes where you need to plant bombs instead of it blowing up once the single point or both points are taken theres a barrage that comes in that kills anyone in the area so it clears out the few enemies in the area and gives attackers time to set new rally points or push
probaby the same way as the rocket arty for each faction is balanced. Despite the jp one beeing 150mm and the german 158mm rockets they all share the stats for the 82mm ones the USSR has for rockets.
It’s like a 500 kg bomb. Although I think the bomb would be even more powerful, since it contains more explosives.
3-4 such shells are more than normal.
OP’s suggestion is to replace arty with battleship barrage. What you are saying is a completely different function instead of balancing OP’s suggestion.
