So it was a great Idea and applauded when Ukraine was given upgraded T 55's a few months ago lol. But now its a horrible idea.
Upgrade them with modern fire control systems, reactive armor and place with infantry platoons when clearing out trenches, fortified positions. The tanks act as cover for moving infantry units , and 100 mm is great for clearing out embedded troops. Of course Americans think that billion dollar F 35's and big air craft carriers will win this war lol
Plus Russia has millions of 100 mm rounds already produced. While the west is scrambling to manufacture rounds which are dwindling very fast
