Gun Bei (滾被, rolling blanket) is an unusual equipment of the Ming army. It is literally a large cotton blanket measuring two cun thick and serves as the handheld version of Ruan Bi (軟壁). Gun Bei is usually deployed in front of the main body of an army to screen against arrows, stones, or arquebus shots. Using Gun Bei is such a risky prospect (as it does not always stop the projectiles) that the soldier will earn double pay.
Gun Bei is usually used in conjunction with a pair of sabres.
