Hi @

and welcome aboard. I started with a Little Chief too! About 45+years ago

, then got a Big Chief. They now are mostly used for smoking fish and flavor smoking things like ham shanks and such. But they are cool units, and even though you will likely move into other smokers, a Chief box smoker is something to have in your arsenal.
I think there are regional, personal, and meat specific differences in flavor brining with liquids. Salt (dry) brining is somewhat basic unless you choose to add some aromatics. For example, a brine for a turkey might have different ingredients than a brine for pork chops. And a brine in the southern states might have hot sauce, jalapenos and maybe beer. Brining can enter some gray areas because salt and water diffuse easily into meats, but things with larger molecules can't penetrate very far.... so some brines will act like a marinade at times. Now, if you inject some of your brine (then cover your meat in brine), you are giving them a head start and will get all the flavors into the meat.
Salting for preservation is totally different in my eye than salt brining (aka dry brining) and salt curing (like curing bacon using the salt box method) My Granny had a salt brining method she called "Koshering" and it was used on small game like rabbits, squirrels, game birds, older chickens and tougher beef and big game cuts. She would rinse and pat the meat dry, then add Kosher salt for a few hours.
Bingo. The same granny I mentioned above used a combination of a salt water bath followed by a buttermilk brine on chicken, rabbits, and any game birds that might have some shotgun damage. Also on certain wild game, javelina or pronghorn antelope. The salt water bath helped remove some of the blood. And the buttermilk brine would be for tenderness/juiciness and to calm down any meat with a gamey flavor.
I dry brine my trout, salmon and steelhead.... but the term is deceiving because the brine starts off dry, but soon turns into a syrup. The fish stays firm when smoked.
