While you're at it, you can think about adding new magazine(s?) to add the missing recipes for Aerosol Bomb, Pipe Bomb and Flame Trap - these are currently the only recipes that don't spawn in form of magazines and have to be chosen from the beginning (as a profession) I'm pretty sure I've found an Aerosol bomb recipe... I think it was in a previous MP game, but I assume it would spawn in SP also.
