First, I should say I have played the game for a month and I really like it very much ,so I want it to become better.
I am familiared with the weapons of Japan forces in world war 2.Their fire power is weak so they were heavily beaten by the American forces on the island of pacific ocean.But one thing cannot be ignored that they got a special grenade launcher like light mortar which aslo did a lot of casualties to the Americans. (we can see it in the film "Windtalkers")Japan forces were equipped with a large amount of this weapons,but this weapon is not showed in the game.I really think it is a pity.I hope it could be added to the japan forces in the patches later.
