or guard of honour, with a chamois leather sword knot. Swedish Mounted Cavalry Band Musicians with the equivalent rank of soldiers wear red epaulets instead of the dragoons' white to distinguish them on the battlefield. They also wear white braid Prussian styled wings to even more be distinguished. Musicians with the rank of officers or specialist officers wear the same uniform as officers, with the exception of having a blue and yellow cockade instead of a full yellow (stating that they bear civil ranks). Changes in 1928 As of 1928, the Life Horse Guards (1st Cavalry) and Life Regiment Dragoons (2nd Cavalry) were amalgamated into the Life Regiment of Horse (1st Cavalry). The uniforms remained mostly the same as of the old 1st Cavalry, taking the traditions with some additions from the old 2nd Cavalry. The Officer's Frock Coat m/1858 was middle blue (slightly lighter) for the 1st Cavalry, but after 1928 the model of the 2nd Cavalry was adapted, which is dark blue with black lacing. The helmet m/1879-1900 of the 1st Cavalry was added a golden laurel wreath, taken from the helmet of the 2nd Cavalry. This was added for all ranks. The helmet with its addition is now called helmet m/1879-1900-1928. The helmet m/1879-1900-1928 also got the straw wreath from the 2nd Cavalry (originally from "great battles", but nowadays said to be from the Battle of Lund) put under the chin strap on the right side of the helmet for soldiers. Officers still wear a yellow silk cockade. The straw wreath was also put on the forage cap for all ranks, under the cap button badge. The officer version of helmet m/1879-1900-1928 was added the chin strap from the 2nd Cavalry made of lion mascarons and embossed plates. This change was added on paper at the time, however not adapted until later on. Changes since 1950s The military ranks of the Swedish Armed Forces have undergone changes throughout the years. With the introduction of a two-officer-system in 2009 (which distinguished between tactical officers (OF-1/9) and specialist officers (OR-6/9)) the following innovations were made: Specialist officers now have a helmet plate in white enamel, while tactical officers still wear blue enamel (2009). Specialist officers' uniforms are based on that worn by sergeants. New epaulettes based on historic models have been reintroduced for specialist officers. One to three chevrons are used instead of diagonal stripes by lance corporals (OR-3),
