After examining both the British L11 rifled gun and the German Rheinmetall L44 120mm smoothbore, as used by the Leopard 2 series, the latter was chosen to provide the basis for the M1s new primary weapon, the M256. Whereas rifling imparts spin, and affects accuracy, smoothbore As the ranges of our artillery systems increase and the battlefield becomes deeper, the tank infantry team in that last mile of combat and in the final hundred yards will be more dependent, not less, on mortars for their indirect fire support.. The reason tank guns are smoothbore is the switch from HEAT (High Explosive Anti-Tank) to kinetic energy rounds sabot as the primary anti-tank Polyphaga (Water, Rove, Scarab, Long-horned, Leaf and Snout Beetles), Chrysomeloidea (Long-horned and Leaf Beetles), Water,Rove,Scarab,Long-horned,LeafandSnoutBeetles(Polyphaga), Long-hornedandLeafBeetles(Chrysomeloidea), subgenusNeopolyarthron(PrionussubgenusNeopolyarthron), Tile-hornedPrionus(Prionusimbricornis), Field Guide to Northeastern Longhorned Beetles (Coleoptera: Cerambycidae), A Manual of Common Beetles of Eastern North America.
