I think there are 12 tanks in a Polish tank company.
Different countries have different platoon, company and battalion organisations.
At your service Sir! A US Army Tank Company currently consists of 14 tanks. They seldom work as pure tank Companies, since we generally operate as teams or task forces , a mixture of weapon systems (tanks/brads/artillery etc...)to accomplish missions. I don’t know the current size of a UKR tank company, but it is a former WP nation, and their tank companies were usually smaller.
IMHO, this is a profoundly stupid idea; those Leo’s will be broken or dead in short order. Sad end for those noble beasts.
