I put together 5 TAM tanks tonight. These are the medium tanks used by the Argentinian Army. The vehicle is based on the Marder APC with a turret that is based on the Leopard 1A4.
To make these I used GHQ Marders (N41) and turrets from GHQ Leopard 1A4s (N72). In reality the turret on the TAM has a slightly different shape to the back half of the turret, but the standard GHQ Leopard 1A4 is close enough in my opinion.
