WW2-Content Pack > 1.When I craft the air craft ,every aircraft don't need gun.
2.Tank won't get damage when aircaft is booming.
3.Tank won't get damage when it touch off the anti-tank mine.
4. Why the Machine gun of Janpan(Type99) is white when it is builded on the
block?
5.The Trenchgun's sound is strange(loading and shooting).
6.It is lag when I use the warship of Germany(S-100 schnellboot).
7.All of Machine guns will float when it is shooting.

1.Can you change over the sound that every gun? They sound
strange(1.8.0version).
2.Can you change the skin of flag which print on the Janpan's tank? Let it look
like this > https://goo.gl/1S6Ud7
