For ground forces' officers, rank insignia are brass on a red background; for the air force, silver on a blue background; and for the navy, the standard gold worn on the sleeve. Officer insignia are worn on epaulets on top of both shoulders. Insignia distinctive to each service are worn on the cap (see fig. 15). Enlisted grades wear rank insignia on the sleeve, halfway between the shoulder and the elbow. For the army and air force, the insignia are white with blue interwoven threads backed with the appropriate corps color. Navy personnel wear gold-colored rank insignia sewn on navy blue material. From the formation of the IDF until the late 1980s, sergeant major was a particularly important warrant officer rank, in line with usage in other armies. However, in the 1980s and 1990s the proliferating ranks of sergeant major became devalued, and now all professional non-commissioned officer ranks are a variation on sergeant major (rav samal) with the exception of rav nagad.
