There are super-heavy tanks/ships, jets, rockets.
and even rocket interceptors and atleast for the japanese the kamikaze rocket Yokosuka MXY7 Ohka. Kamikaze missions and this "vehicle" is unlocked via a japanese national focus and not availabel by default and other nations wont even get the option to do it.
Their focus tree gets a pretty unique part called "Spiritual mobilization". It will both give more research options as well as improving the average soldiers morale, unlocking kamikaze missions, and if both research and warrior traditions tracks are completed unlock special rocket powered suicide crafts (
MXY7 Ohka) which will be very hard to intercept due to their speed.
I dont know if germany gets its german "equivalent", which is a remote controlled glider bomb remote controlled from the mothership (dornier bomber) tho, which you can see below and is called the Fritz X.
In the end that would rather fit in better as a tech or maybe even as a national spirit similar to the "long lance torpedo" focus the japanese get for their torpedos, that strongly boosts naval strike for naval bombers rather than being represented as a independent unit tho.
There wont be any biological warfare in the game nor will there be any dicussions about it on this forums tho, since it is against paradox's policies and forum rules.
