the Indonesian Amphibious Tank, type 32. This vehicle is perfectly suited to it's combat environment of luscious jungle and regular river or swamp crossing.
About this creation
it may look a bit comical with its 6 huge wheels for turning the treads, but they serve a purpose: the larger wheels make this tank a lot faster than if it used small gears, and mud is much less likely to clog it.

The turret is a pretty basic standard double 52mm cannon, good against most vehicles and, surprisingly, infantry too. The top of the turret is covered in a variety of equipment, including an LMG, a satellite dish set-up, a rangefinder, and a camera periscope for when the vehicle becomes submerged.
The wheel system. As you can see it is a smaller wheel inside of a larger one :P
And a little curved ladder at the back, using a curved banister.
