Okay, as I'm trying to learn 5e, and coming from a 2e and 3e heritage, I'm seeing a HUGE gap as I read through the Player's Handbook.
Are there no skills/proficiencies at all for a character to know a profession?
There is the short list of very broad skills for characters, and craft skills (and many thieving skills) seem to fall under proficiency with the tools of that trade. . but what about professions that aren't centered around a toolkit?
For example. . .
If a player or DM wanted a PC or NPC to be proficient with soldiering, to know how to function as a professional soldier, to know drill and ceremony, military procedure and bureaucracy, they had options in previous editions.
In 1st and 2nd edition, they could have a Soldiering Non-Weapon Proficiency or a Soldier Secondary Skill.
In 3rd/3.5 edition, that would fall under the Profession (Soldier) skill.
4th edition didn't have Profession skills because WotC infamously said they "weren't fun" and that any games using them weren't fun. That sort of attitude was on the long list of reasons I ignored 4e.
. . .but I'm looking at 5e and trying to see how this would have any sort of profession related skill. The closest I can see for my example is the Soldier background, but that doesn't give any special proficiency on any skills related to soldiering, and there's no way to gain anything like this after beginning the game. There's the training option for languages and tools, but that wouldn't cover a profession.
It seems like a gaping hole in the skills system. So, is there an option I'm overlooking? Is there some rule I'm missing?
