Not that close. Cenet uses tanks as infantry support and for operating independently. Infantry support is conducted primarily by the light tanks, with tank squads consisting of both medium and light tanks in a 3:6 ration of medium to light.
Cenet think about Blitz ? Before WWII almost all nations use tanks only as infantry support only those of future aggressors ( Nazi German and Soviet Union ) create fast tank units for attack. If this is tank design before war, you need to think like everybody before war. Not like man who know there will be Blitz, there will be T-34, Panzer V ect: Because for now your tank don't have a sense, he is a 100% attack tank, who you want to invade ?
Why not use a Christie suspension? It's got more stability and compression. Weight, being the biggest disadvantage, is an irritating but necessary evil.
I have corrected the fonts on the drawing.
Christie suspension was build only for one thing ... speed. Speed and good roads.
Soviet buy that suspension system and build massive numbers of BT tanks with it because that type of tanks would take a great revolution to the shores of Atlantic. BT and T-37 was tanks no to use in Russia but on Poland, Germany, France where there was a good road system. British also use that type of suspension in cruiser tanks, well because they were a cruiser tanks and need to be fast. Again I will ask you what highly development country Cenet want to invade ?
And still you have not answer about that unusual for that time 70mm gun.
