get the gun, then turret and then hull

the hull, while 15km/h slower than the Contender E1 has better armour protection that can block some shells

the turret has 2-25x zoom which is amazing for sniping as well as two spaced out blowout ammo racks, decent armour and a high reload multiplier of 1.5 with the only downsides being its poor gun depression and easily identifiably weak spot

the gun has only slightly more overall APFSDS penetration than the 105mm OTO but a noticeably shorter reload
