Ranged attack is a special ability of creatures, which allows them to attack without engaging into hand-to-hand combat. Visually typical ranged creature is armed with bows, e.g. Archers and Elves, but there are also several creatures, that use some kind of magic, like Monks or Titans. However, this is only a visual effect and has no affect on the gameplay. When attacking in melee, most ranged creatures suffer melee penalty, which halves their damage.
