Some women served in various positions in the IDF, including infantry, radio operators and transport pilots in the 1948 war of independence and "Operation Kadesh" in 1956, but later the Air Force closed its ranks to female pilots, and women were restricted from combat positions. There is a draft of both men and women. Most women serve in non-combat positions, and are conscripted for two years (instead of three for men). A landmark high court appeal in 1994 forced the Air Force to accept women air cadets. In 2001, Israel's first female combat pilot received her wings. In 1999 the Caracal company was formed, as a non segregated infantry company. In 2000 it was expanded into a Battalion (called The 33rd, for the 33 women killed in combat during the War of Independence) since then, further combat positions have opened to women, including Artillery, Field Intelligence, Search and Rescue, NBC, Border Patrol, K-9 Unit and anti-aircraft warfare.
