Can we keep the RHA coat because reasons, and also do you still want this guidance scrambler because I mentioned it last time under the name ECM and it got shot down.
Also you're getting a coaxial 20mm rotary cannon so I hope you like that.
For other, special armaments I was thinking one bigforget 205mm, some type of high-power lasers, chemical or otherwise, of varying affects. Perhaps a short-barreled mortar/howitzer variant, basically in line with a baneblade. There is also an 88mm rotary cannon from Naval Warshio Gunner, and perhaps 105's in ZSU-23-4's format, perhaps up to 6 barrels.
Depends upon how obscene you want this thing.
