Wasn’t this created to test new APFSDS and imitate enemy armor?
There was also a Type 69 with add-on armor to imitate a T-80U frontally.
Also was equipped with Type-99 tank’s FCS components (sights, ballistic computer) to test durability of those under fire.
Not much from Hungary probably, but Romania can bring some stuff:
TR-85M1
TR-125
MLI-84M1
MLVM
Piranha V
Lancer C
F-16 with AIM-9X)
Although if plans comes true we can see more things like Romanian Abrams and K2, maybe Hungarian KF51 and Skyranger.
I mean, if ya wanna get reaaaaaaaally specific, Romania technically can get the Leclerc, as they trialled it. Also the Abrams too I guess? For air they could have the F-16AM which they recently received.
