Armour-piercing discarding sabot higher muzzle velocity. Unfortunately the low sectional density of the APCR resulted in poor carrying power (high aerodynamic drag), losing velocity and penetration rapidly over distance. To overcome these limitations the British devised a way for the outer sheath to be discarded after leaving the bore. The name given to the discarded outer sheath was the sabot (a French word for a wooden shoe). For APDS projectiles the sabot is also known as a pot, as the sabot resembles a flower pot in shape. The APDS has the advantages of the lightweight projectile with regards to bore acceleration and high
Spanish playing cards the "sota", which is similar to the jack/knave and generally depicts a page or squire, the "caballo" (knight, literally "horse"), and the "rey" (king) respectively. There are instances of historical decks having both "caballo" and "reina" (queen), the "caballo" being of lower value than "queen".

It is also possible to find 52-card French decks with Spanish pictures. These have English corner indices which means the Knight will have the Queen's "Q" index. Historically, Spain was
