Ok I just want to point this out.. At chapter 131 on middle of Japan(the S-rank gate) you could see two 1944 king tigers(Tiger 2 a german heavy tank from WW2). Weirdly they call it modern "firearms" even though it was placed in a more futuristic setting. On the side note why the hell are german tanks there?! Should it have been Type 61's or Type 10's which are Japan's well known MBT's? Sorry for being a smartass but yeah.. Just wanted to point this out
