Midgame Medium

Lower armor by one to save steel, and if you can, swap wet ammo to easy maint.

most unoptimal hoi4 build i've seen all week. too expensive, actual good medium shiuldnuse riveted, maybe welded, never use cast unless on heavy's... hotwizer might be good yet you still shall get yourself some piercing, at least using medium cannon. also dont use HMG or cannons, theyre shit and make your tank worse really, not better on 90% of situations (limited industry, not enough machines, limited resources). better idea is to make 1940 chasis with 3 man turret, medium cannon, angled riveted armour, easy maintanance, christie, gasoline and +4 armour, +3 engine. you get 60 armour tank, 8kph, 80% reliability, 20 soft, 15hard, 60 pierc tank which costs 10.2IC and 2 steel 1 tungsten. it in fact works even better againts ai, cuz you dont need perfect tank, you need many of them, that one hits optimal spot of economics and performance

this would be good if not for the cast armor. SPG is much better than medium tank. I'm guessing you're playing singleplayer. Never use regular tanks, always use their variants (until the next patch omes where they get nerfed). Armor variants get free stats from their designation + they get buffed by doctrines in usefl ways (atk stats, reli, speed etc) contrary to regular tanks. don't exceed 4 armor clicks, the 5th requires a tech + makes the tank cost 1 steel more. NEVER use cast armor. Always stay on riveted (DON'T sleep on a -20% cost) except for specific armormeme where you can use welded. You have radio 2, by that point you should have howitzer 2. Speed is basically up to your preferences. Reli is more based on where you fight : 50% is acceptable for a singleplayer frontline tank if you don't fight in desert, mountains or jungle. Good stuff : - Using howitzer and secondary HMG. Perfect. - Using 3man medium turret. Perfect - Using radio tech. Very good.

By the way, that amogus guy is wrong on multiple points : - for singleplayer the howitzer is currently meta because AI tanks don't exceed 45% hardness and are so rare that hard atk doesn't matter (around 10% of the AI's units. Don't exceed 50% hardness until mass mechanization which comes around 1955') - Piercing doesn't matter. You will pierce AI tanks with just one regimental AA until they start adding mech to their units. By then it doesnt even matter. - The current Meta SPG cost around 13 IC with easy maintenance, has 85+ soft atk and 30brk and it rolls everything like butter. A 10IC tank with 20 soft and 15hard is NOT worth it
