This was suggested before and i think one of the update logs it said that tank mg's could do damage to aircraft. Later on i witnessed it not working and i speculate it was shadow removed. I think this is a great suggestion for actually using normal tanks rather than heavytanks. It is not really eye soring to see 300 heavytanks and not a single normal one but tanks are super rarely used exept if IFV's are not in stock or something else. Why this should get added? As we know heavytanks are really bad at defending air targets because of its cannon loading and slow rate of firing. And i like it that way for myself but normal tanks which are a lot weaker which have a more faster rate of fire still is not very good at taking air targets and will get destroyed from 1 strike of a bomber. Tank mg's will provide air defence and would be realistic like for one instance in world war two a tiger 1 (i know it is a heavytank) shot down an aircraft with its machine guns (and cannon which was a very lucky shot. The crew commander was simply annoyed about the soviet aircraft. More info in wikipedia) but americans (like the m4) had anti air machine guns in the turrets which shows this not being unrealistic. There might be people who thinks that anti air trucks wont get used but they are still going to be used if this gets implimented by protecting heavytanks. Also 1 or 2 machine guns on tanks cannot defend a whole 3-5 heavytanks (typical division in movecraft sieges) anti air is already quite overpowered by removing any air superiority even if there are 300 aircraft because of its really fast rate of fire and spread but tank machine guns has a good rate of fire but no spread and with aircraft flying at speeds of 15.5 blocks per second it will need skill to aim it. Please i would be very grateful to hear about this and things that should be changed.
