Female legislators took advantage of the momentum to draft a bill allowing women to volunteer for any position, if they could qualify. In 2000 the Equality amendment to the Military Service law stated that the right of women to serve in any role in the IDF is equal to the right of men. Women have served in the military since before the founding of the state of Israel in 1948. Women started to enter combat support and light combat roles in a few areas, including the Artillery Corps, infantry units and armored divisions. A few platoons named Karakal were formed for men and women to serve together in light infantry. By 2000 Karakal became a full-fledged battalion, with a second mixed-gender battalion, Lions of the Jordan (אריות הירדן, Arayot Ha-Yarden) formed in 2015. Many women also joined the Border Police. In June 2011 Maj. General Orna Barbivai became the first female major general in the IDF, replacing head of the directorate Maj. General Avi Zamir. Barbivai stated, "I am proud to be the first woman to become a major general and to be part of an organization in which equality is a central principle. Ninety percent of jobs in the IDF are open to women and I am sure that there are other women who will continue to break down barriers." In 2013 the IDF announced they would, for the first time, allow a (MTF) transgender woman to serve in the army as a female soldier. Elana Sztokman notes it would be "difficult to claim that women are equals in the IDF". "And tellingly, there is only one female general in the entire IDF," she adds. In 2012 religious soldiers claimed they were promised they would not have to listen to women sing or lecture, but IAF Chief Rabbi Moshe Raved resigned because male religious soldiers were being required to do so. In January 2015 three women IDF singers performed in one of the IDF's units. The performance was first disrupted by fifteen religious soldiers, who left in protest and then the Master Sergeant forced the women to end the performance because it was disturbing the religious soldiers. An IDF spokesperson announced an investigation of the incident: "We are aware of the incident and already began examining it. The exclusion of woman is not consistent with the values of the IDF." Defense Minister Moshe Ya'alon has also arranged for women
