Development
When the United States entered World War II in 1941, all infantry were issued with the Mk 2 fragmentation hand grenade. Owing to its hand-thrown nature it had limited range of 35 yards (32 meters) and could not be used against armored targets. To keep its weight down it had to have a small charge, with a fatality radius of just 6 yards (5.5 meters). For longer ranges rifle grenade attachments were available for the M1903 Springfield (M1 grenade launcher) and M1917 Enfield (M2 grenade launcher). These rifles were rare as they had been all but replaced by the M1 Garand by 1943. To rectify this, U.S. Army Ordnance designed a new launcher attachment for the M1 Garand, designated the M7, which could fire much heavier grenades up to 250 yards. M7 compatible fragmentation grenades had a fatality radius of 11 yards (10 meters). It entered production and service in 1943.

Famous quotes containing the word development:
“Information about child development enhances parents’ capacity to respond appropriately to their children. Informed parents are better equipped to problem-solve, more confident of their decisions, and more likely to respond sensitively to their children’s developmental needs.”
—L. P. Wandersman (20th century)
“The man, or the boy, in his development is psychologically deterred from incorporating serving characteristics by an easily observable fact: there are already people around who are clearly meant to serve and they are girls and women. To perform the activities these people are doing is to risk being, and being thought of, and thinking of oneself, as a woman. This has been made a terrifying prospect and has been made to constitute a major threat to masculine identity.”
—Jean Baker Miller (20th century)
“John B. Watson, the most influential child-rearing expert [of the 1920s], warned that doting mothers could retard the development of children,... Demonstrations of affection were therefore limited. “If you must, kiss them once on the forehead when they say goodnight. Shake hands with them in the morning.””
—Sylvia Ann Hewitt (20th century)
