its such a difficult question, by way of tanks it has to be the T34, simple effective and way ahead of anything else on the battle field at the time, ultimate tank, toss up between challenger 2 and leopard 2, best APC, now that is difficult, 432 classic easy to drive fast enough and strong enough, ot90 and BMP fantastic machines plenty of power and go like stink...not the best protection in the world, and I could go on and on, JCB 360 great machine, take your pick on size...i have js130 superb machine has been working for me nearly every day of its 10 years or so with me...she is getting old now and ready for a new one, will likely go for a slightly bigger one next time.
