Solution
b=abs(z)
if max(b,abs(y-4))<2 and x>-2 or abs(y)+abs(x)<6 and abs(y)<4 and(b>4 or y>-2)then return b<5 and 11 or 3 end
How it works
The tank is two pieces: a chunky diamond-shaped hull and a little turret sitting on top.
The hull is a diamond in the x-y plane (abs(y)+abs(x)<6) capped at 4 units tall (abs(y)<4). The undercarriage gets carved out where the belly would be (abs(z)<5 and y<-1), leaving the wide tracks poking out on both sides. Those track edges (abs(z)>4) get painted BLACK while everything else is GREEN.
The turret is a compact cube centered at y=4, using max(abs(z), abs(y-4))<2 as a clean Chebyshev distance check. It extends from x=-1 onward (x>-2), giving the barrel a slight forward lean.
The whole thing fits in one if statement by or-ing turret and body together, with a shared color expression at the end.
