In the Wehrmacht, the traditional military salute was required when wearing headgear, but the Nazi salute was performed when not wearing headgear. The Wehrmacht eventually fully adopted the Nazi salute following the 20 July Plot. East German National People's Army followed the Reichswehr protocol. In India, the three forces have different salutes with the Indian Army and the Indian Navy following the British tradition. In the Indian army, the salute is performed by keeping the open palm forward, with fingers and thumb together and middle finger almost touching the hatband or right eyebrow. This is often accompanied by the regimental salutation, e.g.:"Sat Sri Akal" in the Sikh Regiment. The Navy salute has the palm facing towards the ground at a 90-degree angle. The Indian Air Force salute involves the right arm being sharply raised from the front by the shortest possible way, with the plane of the palm at 45-degree angle to the forehead. In Indonesia, executing a salute has its regulations. For members who are part of a uniformed institution and wearing a uniform will implement a gesture of salute according to the regulations of the institution the member is part of. In this case, personnel of the TNI and Indonesian National Police are to implement a hand salute by forming the right hand up making an angle of 90 degrees and is bent 45 degrees, fingers are pressed together and placed near the temple of the right eye, palm facing down. For personnel wearing a headdress is to place the tip of the right index finger touching the front right tip of the headdress. Other uniformed organizations/institutions which are not part of the military/police will implement a hand salute as done by members of the military/police. The command for this gesture in Indonesian is "Hormat, Gerak!". Military and police personnel armed with a rifle during a ceremony will implement a Present arms while personnel unarmed will execute the hand salute. This is done during the raising and/or lowering of the national flag, rendition or singing of the national anthem, and when saluting to a person or object worth saluting. In the Israel Defense Forces, saluting is normally reserved for special ceremonies. Unlike in the US Army, saluting is not a constant part of day to day barracks life. The hand salute is still performed according to the army "Infantry Training - Formal Instructions" regulation, chapter II, section 12 (1939) ""The salute is completed sharply ... bringing the right hand vigorously to the visor of the headdress, with the tip of the fingers over the right eye; the hand in line with the forearm, with the palm facing downwards, the fingers joined and stretched, the index finger in contact with the edge of the visor; horizontal arm, forearm naturally inclined"".
