Criticisms that I would level at the design (please don't take these personally as these are meant to be constructive and help you with future projects) is that at the front of the vehicles the crew compartment has windows but no doors for the crew to get in or out.
Also it seems to have far too many wheels. Unless this vehicle is incredibly heavy I would take off a number of wheels and spread them further apart.
The last thing I noticed straight away is that the radar itself looks featureless and too thin to actually be a radar antenna.
Otherwise I would say it was a very interesting idea.
I think if I was designing such a vehicle now I would probably use a four faced AESA design on a fixed structure. With no moving parts it will be simpler and cheaper, yet in operation you have all directions covered and can scan in any direction electronically simultaneously. To match that performance I would add a few EO ball turrets for ID purposes.
To defend the vehicle I would attach the vertical bin launchers of the SA-15 SAM system that would take target data from the main radar array and the EO turrets and give 360 degree SAM coverage. The advantage of the SA-15 over the SA-19/-22 is that the vertical launch missiles of the former are ready to engage targets from any direction without needing to turn a turret... assuming the main array can perform search, tracking and guidance functions.
Just using the main array also reduces the chances of interference in combat while searching for targets and transmitting that target data to the network while engaging threat targets close to the vehicle.
With the AESA radar LPI modes can be used to minimise risk.
Very nice model... thanks for sharing.
BTW after reading my comments how might you want to improve it?
Perhaps adding Morfei missiles in vertical launch tubes using lock on after launch fire and forget missiles would allow large numbers of threats to be dealt with more rapidly?
