By the way: I've just recalled, that PzKpfw-I in Spain were able to destroy T-26 (15mm armour) using SmK(H) tungstene-cored ammo up to 150 m. A hunting ended, when the Republicans started to keep a distance and use gunnery advantage. So maybe this MG should be given short-ranged Sabot, as an exception? (I don't insist, because it would be fear for Polish tankettes, or even 7TP
)
BTW2: frontal armour 3 of T-26 is too much - but it's another story.
