Leopard 2A4s in the tropics

Singapore appears to be the only tropical operator of the Leopard 2A4s. The other operators, according to a list from Wikipedia are mostly European except for Turkey in Asia Minor and Chile in South America. I wonder if there will be conversation work.

On the next aspect, assuming a 10-tank company, 66-tanks will be enough for 6 companies. Two battalions worth of tanks... How will this be organised? I really have no idea. A tank battalion with two or three mechanised infantry battalions for a brigade? Hmm.. The organisation will likely be different from that of the AMX-13s. The size and frontage given the armament of the Leopard are vastly different, thus probably necessitating a different set of operating procedures and organisation.

Other questions. What of the APFSDS rounds? Tungsten carbide or depleted uranium (DU)?
