Boardgame counters are usually small cardboard squares moved around on the map of a wargame to represent armies, military units, or individual military personnel. The first wargame based on cardboard counters was War Tactics or Can Great Britain be Invaded? invented by Arthur Renals of Leicester in 1911. The first wargame bringing counters to a mass-market was Tactics, invented by Charles S. Roberts in 1952. Traditional wargames typically have hundreds of counters (The Russian Campaign, 225;GI: Anvil of Victory, 856; Terrible Swift Sword, >2,000). Squad Leader had counters of different sizes: 520 ½-inch counters and 192 ⅝-inch, with the different sizes used for different purposes.
