First off I think it´ll be difficult to find any vehicles and tanks in that scale(1:144).
Most tank kits are in 1:35 which is a fairly easy scale to do dio´s in.
Tell us a bit more about what you are trying to do. Do you have an idea?
If you don´t and just want to build a dio of something I´d suggest picking up a cheap 1:35 tank with a couple of figures and start from there.
