I talked about tanks with additional armour before, including the advantages and downsides of this treatment. However, there is one I did not mention.
"5 T-26 tanks belong to the 40th Tank Brigade that carry additional wartime armour screens, ## 4314, 4307, 4312, 4310, and 4394. The armour does not allow dismantling the guns on these vehicles, as the armour is welded on. The military representative of factory #174 examined the vehicle, and concluded that it is necessary to remove the extra armour, after which it will be possible to dismantle the gun.
I ask for directions from factory #174 on how to remove the extra armour."
