Military personnel in uniform are required to salute when they meet and recognize persons entitled (by grade) to a salute except when it is inappropriate or impractical (in public conveyances such as planes and buses, in public places such as inside theaters, or when driving a vehicle).
One notable player, Shawn Kemp, enrolled in college but never played any games due to personal problems. In 1989, a year after his high school graduation, he was drafted by the Seattle SuperSonics. He played 14 seasons in the NBA and was selected to 6 All-Star Games and 3 All-NBA Teams.
In 1974, the NBA's rival, the ABA, drafted high school star Moses Malone. He was immediately signed by the Utah Stars and became the first player to go directly from high school basketball to a professional league. He became an instant success, averaging 18 points and 14 rebounds per game in his rookie season.
