From that segment, so among other things it should be accommodate a ZTZ99A, or three ZBL08 pattern (?) AFVs, or a HQ-9 TEL with two missiles (unsure if it can also accommodate the two additional missiles as standard; this may have been an initial footprint test displayed)
The significance of the HQ-9 TEL is probably the most notable -- as far as long distance strategic deployment goes, the ability deploy a relatively combat ready LR SAM TEL in a regular strategic transport without needing a super heavy transporter (like An-124 or C-5) is somewhat notable.
(For example, I am unsure if Il-76 has the footprint to accommodate a standard S-300 TEL)
