Italian tanks make good inspiration, for Referees who are looking to present the PCs with some bizarre battlefield equipment, to use (flee!) or to fight (near-guaranteed victory!)
The use of helicopters for recon team insertions could be very helpful to military-minded Referees and PCs.
Some adjustments will be needed, when replacing helicopters with air/rafts, G-carriers, armoured shuttles, and drop troops, but at least the basis for some good Traveller military doctrine is available here.
(Grav belt troops are a different kind of fish, though – the ability to get airborne at will is a serous game-changer!)
