Off The Mark: US Revamp: T3 HMC
Great at br 1 without a turret and a short 75mm howitzer and mg in turret this thin skin td/spg would be great. With only a limited crew of 3 and 16 to 24 75mm shells. around half an inch of armor it is no match for a at rifle making it perfect for br1.
BR1 should stay howitzer free, it doesn’t need anything more powerful than low caliber tank guns. Facing seal clubbers spamming 3-inch guns would not be a good experience for new players starting out in br1, especially if they don’t even have anti tank soldiers.
Also historically it could fit a whopping 61 rounds not just 24, source.
