Notes

1. From 1 April 1918, the date of its official formation, until a little after the close of World War I, the Royal Air Force used the same ranks as the British Army. The highest RAF rank held during this period was lieutenant-general.
2. For transliterations, refer to History of Russian military ranks.
3. Austro-Hungarian ranks are shown in both German and Hungarian, as would have been contemporary practice.
4. Military personnel in the Ottoman Empire were assigned different duties according to their capabilities in order to administer the Armed Forces and particularly to be successful in battle. They were given various ranks so that they could conduct relations with each other and be fully aware of their duties. The issue of what sort of duties should be allocated to which unit or to which military institution used to be determined by the ranking within the Armed Forces. In Islamic countries, certain 'degrees', instead of ranks, were given in accordance with the categorization of government duties. In the course of time, these 'degrees' had taken on certain characteristics. In the Ottoman Empire, besides the ranks that were awarded after passing through certain stages of promotion, there was also the rank of "Pasha" that was given directly by the Ottoman Sultan. This rank, which continued until the establishment of the Republic of Turkey, was also given to civilian administrators who were approved of and found suitable. After the establishment of the Republic, the Sultanate was abolished, and the title became synonymous with the General rank, restricted to the Armed Forces only. Paymaster of a regiment - Captain of the Right Wing (Alay Emini - Sağ Kolağası): The rank of the Captain of the Right Wing was very high. The rank of the Adjutant and Paymaster of a regiment was also high but such individuals were not from the military class and they dealt with clerical duties and equipment needed by the regiment. Captain of the Wing - The Captain of the Left Wing- (Kolağası - Sol Kolağası): Captain of the Wing or the Captain of the Left Wing was the senior Captain. If he was educated in the regiment, he was called "Ağa" but if he was the son of a pasha, he was called "Bey".
5. Maréchal de France and Amiral de France were as much a dignity of state as a military title. Thus British Field Marshals consulted with French Generals in 1914. The elevation of Joffre to Maréchal in 1916 actually marked a diminution of his powers of command. There was no Amiral de France alive during World War I.
6. Army/cavalry ranks. Cossack cavalry had distinct ranks below Podpolkovnik: войсково́й старшина́ (Voiskovoy Starshina), есау́л (Yesaul), подъесау́л (Sub-Yesaul), со́тник (Sotnik), хору́нжий (Khorunzhiy)
7. Captains in the cavalry and mounted transport corps in Germanic-derived rank systems were called Rittmeister.
8. Almirante and Marechal were only honorary ranks, not held by anyone during World War I.
9. The Portuguese Army had the particularity of having only a single rank of General Officer. A Portuguese General could be assigned to command from a brigade to the entire Army.
10. The US rank Admiral of the Navy was a unique rank created for Admiral George Dewey after the Spanish–American War; it has never been held by any other person and debate still goes on over whether it was a "five-star" or "six-star" rank. General of the Armies is similarly ambiguous; it was granted to General Pershing at the end of the war, and previously had been held (or a rank of the same name had been held) by Generals Grant and Sherman after the Civil War, but its equivalency to modern ranks is disputed.
11. Like the Portuguese Army, the Serbian Army had only a single rank of General Officer. A Serbian General could be assigned to command from a division to the entire Army.
12. Voivode of Serbia (Field Marshal) was the highest rank in the army of the Kingdom of Serbia. Radomir Putnik held title from beginning of the war since he was promoted in 1912.
