I don't think the Munitions argument is valid. They just reworked Recon support to have 5 abilities which cost or imply the usage of munitions through upgrades or abilities and I think that's fine, and that doctrine has received a lot of positive feedback. The abilities here do not overlap in function, eg. mines, off maps, infantry upgrades, they can be all used at different phases of the game.
To me storm doctrine does not scream scout car that hunts tanks in the puma. Puma could probably work though. Don't see a balance issue or it being useless, may suffer a bit without smoke though.
Command tank and Artillery are in mechanized
Mortar HT and artillery are in festung support.
Assault grens could actually work but they aren't very good
How did U guys forgot this; Stug E & LefH combo MVGame.
