Signal Troops Day (Ukraine)

The Armed Forces of Ukraine (AFU) are the military forces of Ukraine. All military and security forces, including the Armed Forces, are under the command of the president of Ukraine and subject to oversight by a permanent Verkhovna Rada parliamentary commission. They trace their lineage to 1917, while the modern armed forces were formed again in 1991. The Armed Forces of Ukraine are the fifth largest armed force in the world in terms of both active personnel as well as total number of personnel with the eighth largest defence budget in the world, and it also operates one of the largest and most diverse drone fleets in the world. Due to the ongoing Russo-Ukrainian War, the Ukrainian Armed Forces has been described as "the most battle-hardened in Europe," but has suffered many casualties.
