Not sure how this category of vehicles should be used, even though it has appeared popular enough to be tested by the Russians (Uran-9) and Americans (RCV-Medium) as well.
The above vehicle appears to big and expensive to be recon/screen. Flying sensors seems generally a better investment than land ones, especially one that may not be able to get enough bandwidth to make use of the sensors. (I don't think autonomy is in the near future for this category) Long range indirect fires seems generally a better investment in fire support. If you have bandwidth to operate a RCV you have enough to run a battle network to call in fires.
For infantry support vehicles, compact size and terrain crossing ability is likely more important than marginal improvements in firepower and armor.
