In mechanize doctrine,text of JU87 Dive Bombing describe it dropping a 50 kg bomb,but JU87 should at least drop a 250 kg bomb.Also,the maximum of bomb weight,which it can equip,is 1000 kg.
If a JU87 drop and hit target directly With 250 kg bomb(or 500 kg maybe),it can destroy a heavy tank in one drop.
And there still have a bug,JU87 is invisible while dropping bomb.
I think the answer to this question depends on the Stuka version which is wanted by the dev team and the fitting historical facts. On that score we could also talk about a 1800kg bomb ¯\_(ツ)_/¯ btw… that would be really awesome
