As it stands now, the munitions table is extraordinarily limited to baseline ammo which has negligible costs and really doesn't offer much in the way of fiscal award to those who invest in the skill as opposed to chemistry - which has a very powerful economical workflow.
I believe expanding munitions tables for highly skilled users to be able to product vehicle weapon ammunition which is notably expensive would be a boon for the game.
Would it result in an uptick of vehicle combat? Quite possibly, but that would also mean more work for mechanics, and ultimately less chyen going to NPC vendors and more chyen changing hands between players.
(I do suspect this has been brought up before but I couldn't find an appropriate thread)
