Currently when splitting the vanilla technology off into different ones the Schall's Tank Platoon (and dependent mods) don't get the corresponding upgrades, the categories of "autocannon-shell", "cannon-H1-shell", and "cannon-H2-shell" need to be added to the normal cannon upgrades when they exist. See https://mods.factorio.com/mod/SchallTankPlatoon/discussion/5ff0383a6b50a43c6adabfae for more details.j
