US Cartridge, 106mm APERS-T, M581, XM581
This cartridge is fired from 106mm recoilless rifles to cause personnel casualties.
A perforated metal cartridge case is crimped to a projectile fitted at the nose with a fuze adapter. The propelling charge is contained within a plastic cartridge case liner. The base of the cartridge case contains a percussion primer with the igniter tube extending through the propelling charge. The projectile is loaded with 8 grain flechettes packed in separate bays, and also carries yellow dye marker in the two aft bays. The fuze adapter is equipped with four radially spaced detonators for splitting the projectile. A fifth detonator with relay charge is installed for igniting an expelling charge in the base through a flash tube formed by the flechette bays. Two indexing buttons are provided on the forward bourrelet to facilitate indexing of the pre-engraved rotating band with the barrel rifling of the weapon. A tracer is threaded into the base of the projectile.
