75mm Cannons (ALL of them): M64 white phosphorus (WP or “Willy Pete”) round, which proved highly effective in the bocage fighting around Normandy. Looks like the filler is 1.34 lb, 0.6 kg of WP
M9 Bazooka: M10 bursting smoke (white phosphorus) rockets (weight: 3.4 lbs., velocity: 265 feet per second)
These would be really cool additions that would make both American tanks and the M9 Bazooka much more versatile weapons. Being able to lock down areas or harass enemies from a distance that simply lobbing a grenade cannot do. I’m unable to find any WP shells for the 90mm cannon as of this moment
