Right - The basic pattern for the new 1909 imperial army dress blue uniforms, for officers. It is likely that all officers regardless of branch of service wore the same universal pattern dress blue uniform. These tunics came with red or dark blue (red piping added) collars and cuffs. However, a version with green collars and cuffs (for the newly organised Machine Gun Branch), is known to exist.
No other colours have been seen for the cavalry (grey), or engineers (light blue).
Senior Officers wore an additional knotted gold cord below the gold cuff, and collar tape.
Right - The 1909 officers' dress sabre was a German-patterned 'P' guard lightweight curve-bladed sword, generally:
Only one pattern made, indented for all 'Port Epee' officers, except for the rank of Infantry ‘Bascavus’ (Sergeant-major). who typically wore the M1874 Turkish Peabody-Martini yataghan sword bayonets, with a sword knot .
Above/Right - The original picture in Dunya Savasi'nda Turk Askeri Kiyafetleri 1914-1918, Authors Tunca Orses, Necmettin Ozcelik, 2007, Istanbul, has been substantially altered to correct details such as the sword suspension strap made from gold tape with red high-lights (matching the 1909 Brocade Belt design), as well as the use of the French-pattern chain sword sling-strap, that could be used (this itself had a upper hook, to raise the sword up).This looped onto the 1909 Brocade Belt (see below), via the underside 'B' ring (as illustrated by the picture below).
Above/Right/Right - This shows this forward chain with a simple brass hook.Additionally, the 1909 officers' dress sabre scabbard with two sword strap rings, could be suspended from an over the shoulder carry strap (still in use from the 1876-1908 period).
 There is a description of the "Sergeant-Major's red side arm tassel", in the 'British General Staff. (1995) 1916 Handbook of the Turkish Army. Battery Press, Nashville: 136.' Should actually be the 'officer's 1909 portepee. The ‘officers’ above the rank of ‘Bascavus Muavini’ (Assistant Sergeant-Major: two gold bars), used the same officer’s portepee without distinction like the conventionally rated higher officers (Lieutenant etc.). These ‘red tassels’ have never been identified. Period photographs clearly show all officers, wearing the same pattern sword portepee regardless of rank.
Right - The 'D'-Guard short sword for Officers, was introduced in 1909 and was worn by all officers of all ranks, who wore the 1909 'Port Epee' (sword knot) - from the ‘Bascavus’ (Sergeant-major), and right-up to the Marshal (‘Mushir’). It is common collectors mistake to see these as 'NCO swords'.

Above - Post-1909 Ottoman imperial army officer’s brocade belt, with bronze buckle.
Below - The matching portepee (all part of the original set).
1909 Epaulettes used by all officers - Lieutenant’s and above are identical.
It is also quite likely (judging from 1876 period illustrations), the lower grade cavalry officers (3rd Lieutenant), likely used a fringeless epaulette with a red cloth field (unchanged from 1876).
Right - These post-1909 buckles were based on the ‘Mannschaftskoppelschloß 1895–1915’ Prussian buckle .
 Right - An example of the early proof-model for what became the post-1909 (German pattern) Ottoman Turkish ‘Imperial Army’ soldier’s buckles. As can be seen, the Ottoman Turkish script for 'Asakr-i Shahaneh' meaning the 'Imperial Army' is contained in the outside ring. This followed closely the German models for the period.
Right - Extracted from the 'British General Staff. (1995) 1916 Handbook of the Turkish Army. Battery Press, Nashville: 136.'
The 1916 Turkish Army handbook, appears to be based on a much earlier volume written soon after the 1912-13 Balkans war, as there are some clear references to this conflict, as the basis of the information. The book was then added to in 1915, and then 1916.
The post-1908 Turkish Army uniform guild (found in the 1911 Italian army manual for the Turkish army) does not shows red piping and the shoulder boards are shown with round ends.
There is a strong possibility, that there has been a period error contained in the 1916 British version of the Turkish army handbook, which accidentally used Bulgarian boards showen as Turkish ones.
Right - An 1895 Austrian publication, that shows the Ottoman corporal with red piped shoulder boards, and a red number - mistakenly drawn as a Chevron. Significantly, the shoulder board is shown identical to the ones appearing in the 1916 British 'Turkish Army Handbook', following the Bulgarian pattern, with the corners cut.
This suggests that the earliest 'NCO' shoulder boards used were actually surplus pre-1908 boards , with the rank lace added over these. Before the actual rounded end plain ‘branch coloured’ boards (post-1909), boards became available.
 The 1895 use of 'cut-angle' cornered shoulder boars may have been short-lived, as the 1908 reference: Askeri Müze ve Kültür Sitesti Komutanligi. (1986) Osmanli askeri teskilat ve kiyafetleri: 1876-1908 [Ottoman military organization and uniforms] Yayinlari; shows Ottoman Imperial shoulder boards with 'square ends' only.
Right - An example of the post-1909 Ottoman soldiers wool cap, was made with brown fur sides (artificial wool; which is made the exact same way as carpet or rug weaving). Many photographs from this period show hats with ridged sides, likely of woven reed, and identical in size to the fez.
The 1909 hat was given a distinctive top or dome the same colour as the coat collars.
Right - An example of the post-1909 Ottoman officer's wool cap, was made with brown fur sides (artificial wool; which is made the exact same way as carpet or rug weaving). Many photographs, and suviving examples, from this period show hats made from black lamb wool, The 1909 hat was given a distinctive top or dome the same colour as the coat collars.
This is an officers' version and has three lace strips arranged over the dome in a six-point star pattern.
Prior to 1909 the Ottoman army uniform had no specific headgear designed for its uniforms, using the national fez headgeat since the 1830s. The lamb wool hat had been used in various styles since the 1860s for some units. From 1908/09 a variety of new headgear was introduced.
Right - Enver Pasha, likely from his 1908 stay in Berlinas as military attache, wearing a tailored fez or early kalpak cover, incorporating a neck flap - a 'Havelock'  . Identical to the British in Egypt versions, introduced for the fez. The practice of wearing light khaki fez covers began with the British supply of these to Turko-Egyptian and Sudanese soldiers from the 1880s, to cover the red fez worn, and these covers usually had variously coloured flashed to identify individual units.
Right - An earlier 1909 'pointed-top' type of wide-brim sunhat, seen in an illustration of post-1895 Ottoman infantry (Marcel Roubicek (1978) Modern Ottoman Troops, 1797-1915: In Contemporary Pictures. Franciscan Printing Press). From 1909, the use of wide-brimmed sun hats, very similar to the American Montana hat became popular in the Ottoman army, these continued in use throughout WW1.
Right - A high quality kabalak, from 1913 displayed in the National Turkish Army Museum, Istanbul. This not only has a brass spike attached on top, supported by a strong ridged frame. It also displays a quality brass ‘Order of Orta’ crescent badge. The wrapped earflaps are fully lined and edged with tape. The ear-flaps were given a 1cm edging in branch color, and were designed to cross over each other, as these were wrapped around the crown.
 A havelock was a light cloth covering for headgear, hanging well down over the neck, worn for protection against the sun, reputedly designed by Sir Henry Havelock, a British general serving in India. Right - This 1911 Turkish clothing catalogue shows an advert for Officer's uniforms and a tailored cover for the lamb wool 1909 Kalpak, identical to cover worn by Enver in 1908.
The Ottoman imperial army's branch of service colours began simply prior to 1908, using red for all services, except green for the rifles, and light-blue for the engineers. The reforms in 1909, for the brown field uniforms introduced a wider colour scheme: (i) Pashas (Red); (ii) General Staff (Purplish Brown); (iii) Infantry (Dark Green – but this could vary between Dark Grey, and Dark Brown colours); (iv) Cavalry (Silvery); (v) Artillery (Indigo Dark Blue); (vi) Machine Guns (Bottle Green); (vii) all Medical (Black); (viii) Engineering (Light Blue); and (ix) Transport (Orange). In 1916, the colour scheme (in some cases this also specified the particular fabric to be used – i.e. velvet) was extended too – (x) Veterinarian (Black); (xi) Medical Doctors (Blood Velvet); (xii) Pharmacy (Green Velvet); (xiii) Air Troops (Light Blue 1909-1916), then Bitter Orange, 1916); (xiv) Transport (Orange, 1909-1916, then Violet, 1916); (xv) Ministry of War Department (Deep Purple); (xvi) Music department (Dark Yellow); (xvii) Science units (Blue); (xviii) Supplies (Lilac); (xix) Military clerk (Brown Valvet); and, (xx) Accountant (Light Brown Cloth).
