As mich as I like the idea and system at all, I want to see a more „Transformers“ -like mechanic system, not an add on or plug-in system.
For example, the radar on the roof of the truck, should be retractable.
What's on top isn't a radar, it's an electro optical system, possibly a laser designator as well, like Aselflir.
Secondly, every mechanical point you add to a system is another potential failure point, and a maintenance list item. Simpler is better, reliability is better, unless it is absolutely unavoidable to complicate a system.
And, any anti-air system needs to come online in a seconds notice, or, shouldn't have an "off" time at all, especially one that is supposed to be on the frontlines.
