What does the acronym S&B mean?
Sword & board (i.e. melee weapon + shield)
Thank you! 
Very good example I might add 
For a time, I thought this was “Shield and —” and I tortured myself trying to find a synonym of a melee weapon starting with “b”.
Ummm. Shield and blade?
Shield and bludgeoner?
Sword and board rhymes, though, and I’ve heard it since the first RPGs I’ve played.
shield and bae
Most acronyms I researched and discovered the meaning, but this S&B I would never guess,
because I’m from Brazil and I speak Portuguese.
The term actually goes beyond video games and can be found in literature and other media.
