1. The constant battle between armour piercing fin stabilized discarding sabot . 2. The rounds are armor-piercing tungsten penetrator rounds or depleted uranium with discarding sabots . 3. Kinetic energy penetrator rounds consist of a long, relatively thin penetrator surrounded by a discarding sabot . 4. Discarding sabots like used with M1A1 Abrams main gun are more commonplace in precision high-velocity gun munition.5. When first introduced, APDS ( armour-piercing discarding sabot ) rounds were fired using a cylindrical charge. 6. For example, a long line of armor-piercing discarding sabot ( APDS ) rounds was developed by Rheinmetall. 7. Armour-piercing discarding sabot ( APDS ) was initially the main design of the kinetic energy ( KE ) penetrator. 8. Between 1941 and 1943, the British combined the two techniques in the armour-piercing discarding sabot ( APDS ) round. 9. It used a 14.5 mm armor-piercing, fin-stabilized discarding sabot round ( 200 mm long ). 10. The Br-2 was also used in a number of unsuccessful experiments with discarding sabot shells, intended to increase range.
