Tech/Unit Bug?

[necxelos]

I found this little issue and I don't know what kind of bug it is so let me describe:
- Some units produced in factories of tier1 has strategic map icons (and by the look of it stats as well) from tier2 or even tier3. Example: 2 tanks in tier1 UEF land factory.
a) Is this just wrong icon (and units was intended to be a little OP)?
or
b) Is this unit just wrongly produced in tier1 factory and should be moved to the respective (based on icon) tier2/tier3 factory?

[EDIT] And what the "ground tarmac" is for? Seem like a placeholder for something, unless I'm underestimating the power of flat ground on which I can't build anything...
