Description

Nicknamed as Colossus, it's a Grand Assault Tank made by Obelia Empire for a breakthrough tank. It was supposed to be an all in one vehicle, from heavy armored tank, infantry support, and artillery piece. Colossus have 145mm frontal armor, 65mm side armor, and 25mm back armor. Armed with 155mm Howitzer as main gun, housed in massive circular turret with slanted roof for protection, crewed with 4 men crew, 1 gunnery commander, 1 gunner and 2 loader. For secondary, it's armed with a 75mm Cannon housed in smaller circular turret facing the front, crewed by 3 men crew, 1 gunner, 1 loader and 1 gunnery commander. Beside that, there's one 30mm cannon facing the back of the tank, manned with 1 crew. For even more firepower, 4x 85mm Cannons facing both front and back (2 each) armed in a long and large sponson, manned with 2 crew each gun (8 in total), 2 hull commander that command all crew also present to improve crew effectiveness, they are responsible for everything. In the very front, there's 1 driver and 1 radio/14.7mm MG operator, totalling in 19 crews.
With massive size, Colossus posses an imposing silhouette in it's era, with armor that couldn't be penetrated my most guns, it's a nightmare for any enemies that meet it. Weighted around 90 tons, powered by new engine that's capable to drive it's around 15kmph in smooth road, around 10kmph in rough terrain.

History

The year is 1920, the Royal Army Ministry request a new vehicle that could fit nearly all role in the battlefield, from infantry support, heavy tank and artillery piece, and it has to be under 100 tons. So both newly formed Kola Arm Industry and Myria Heavy Factory works together to made the first mockup, without turret, the Concept 18A, which immediately approved for further development. Second variant which is the Concept 18B added a main turret that housed 105mm Howitzer, but this deemed to be not enough, so in the third variant, the Concept 18C, it was upgunned and uparmored, housing multiple high caliber weapon and the new 155mm Howitzer.
The final tank finished in 1928, with a name C.18C/28, nicknamed "Colossus".
In 1930, Colossus was modified with extra spaced armor and new engine, and sent to its first and official deployment supporting the Imperial Royal Legions. However, lack of mobility and huge silhouette prove the tank's inability to keep up with infantry, especially it's limited number made it unable to work in group.
The only variant scrapped in 1937, changed into smaller and better heavy tank and assault tank, thus changing the Empire armored warfare doctrine.

Notes

Sorry, This turns to be not too mobile friendly, it has too much performance cost, I've tried to remove most of the part's drag to reduce lag, it's still playable in my Samsung A04, but i don't know in other phone

Anyway, enjoy!
