What really helps is to picture how a resin printer works.
- The build plate moves up from the resin and peels each cured layer from the FEP.
- The layers have to be supported during the print so support placement is important.
- The surfaces facing the build plate will have a lower quality than the ones facing the screen.
You could probably get away with printing it as a solid object if printed at a slow speed, but it may end up looking like
Dagor that Ramba got with difficult to remove supports.
For this vehicle, It looks like it's 150 - 170mm long, so it will be best to print at an angle and support it well. I would separate the wheels and all the dangly bits and print those separately. The exhaust protection grids may be OK as is. I would the hull as a hollow object, mainly because of the weight; give it 2-3 mm thick walls and make sure that there are sizable vent holes to reduce or eliminate any suction forces on the FEP. The turret ring cover can be printed separately as well, and just add a big hole in the bottom and print plug for it on the same build plate.
