There's yet another self-propelled anti-air gun upgrade which adds a couple very short range air defence missile launchers. We've seen this on the American LAV-AD (combined from scratch), a Gepard upgrade package (addition of Stingers), Tunguska (combined from scratch), some ZSU-23-4 upgrade packages, Chinese Type 95 before.

I suppose it's now safe to say that the majority of modern army SP VShorAD assets are a tracked vehicle with light armour, a turret, a radar, a FLIR, a laser rangefinder, at least two 25-35 mm barrels and at least two missiles.
The division of labour is between the cannons for shorter range air defence and defence against ground threats and the missiles for greater range. The typical missile is an ordinary ManPADS with passive infrared/UV seeker and thus susceptible to the countermeasures which were developed against this kind of missiles since the 80's.
Curiously, the Bundeswehr insists on missile-only solutions such as Ozelot (Gepard is retired). I hope they will revise this, for autocannons aren't obsolete; they provide a chance to kill a flying object at much lower costs. This is essential against cheap drones.
I would prefer a mix of versatile 76 mm rapid fire guns with high maximum elevation, laser beam rider missiles (counter-platform) and radio controlled missiles (cheap counter-PGM) instead, but there is no budget for this.
