After their loss in the Malician war against their own people, Trenchea decided to make a new more modern MBT due to the rising threat of Anzhao’s Chessiour mbt series, this is where the development of the KTF series were started. Multiple KTF series were created, mostly experimental but some actually pass the selection and become Trenchea’s mainline MBT’s, one of em were KTF-3. KTF-3 is a third generation mbt featuring the 105mm KM-12 for their early generation and the later generation were equiped with a bigger gun as big as 125mm. Their main strength isnt their armour or firepower, rather its the speed. These MBT rely 90% of their survivability on their speed reaching up to 80-92km/h, which during that time is really fast compared to Anzhao’s slow moving early chessiour unit.

This units later engaged in multiple war during the great war period or known as the cold war period such as Second malician war, Augte-Anzhao war, trainbonyia invasion to Celeste and more. Due to this, trainbonyia which at that time was still using some old units from the malician and the first great war at the early state was offered with the KTF-3A, an older model but still works. KTF-3 has been going through alot of upgrades and stuff, it was great for its time but it was later replaced with the TB-22 and the KTF-9’s due to the KTF-3 not being relevant in the newer more dangerous battles and war anymore and was later phased out by Trenchea silently, even tho some country still operates it like augte vaesha and Celeste republic.

Note: trainbonyia at this timeline still uses the R-54 direwolf and some other cold war tanks and not the modern MBT that much so thats why i said they still uses the old units from the malician war and the first great war
