This is the earlier of the 2 challengers that I've built. Also from Tamiya. More equipment added to this one, e.g the combat ration boxes, tarpulin covers, etc. I did a bit of modifications to the tank commander: the arms were heated and bent slightly inwards so that it would seem like the commander was taking up observation position and reporting at the same time. The loader figure was an additional resin figure which I happened to come across one day.
