I reckon the ammo ToT could involve several types: V-LAP/HE ERFB RA/BB for the 50+ km range coverage plus various guided types, especially laser (to work in tandem with the Army's drone ops) and GPS/INS. If HIT's 155 mm gun pans out, the Army could start moving the bulk of its artillery to 155 mm and 105 mm (for lightweight applications) and, in turn, induct V-LAP and guided shells service-wide. It's a huge capability jump, especially when combined with the large guided-rocket (Fatah-1 and A100), drone acquisitions (for both ISTAR and attack), and 122 mm guided rockets.
If the Army's syncing with the PLA, I'd probably keep an eye on the VT5 at this point.
