Puncher vs Slugger vs Brawler / Swarmer vs Infighter

[GrandpaBernard]

What do you consider to be the differences between a puncher, slugger, and brawler? How about swarmer vs infighter?

[Suckmedry]

Puncher means a guy who can punch, it isn't a comment on their style. Brawler and slugger indicate that they are crude fighters as well as having a good punch.

Infighter means a guy who can fight in close good, swarmer is a guy with a high workrate, not neccessarily on the inside.
