O.K. of all the 255,000 registered users only these few brave soles will tell us what they think a "good" MBT is?

I'll be one of those brave soles

I think a good MBT has to have great firepower,Speeds a must,small size is good,armour has to be good but cost affective,maintenance must be quick and simple,range is a must, as for weight that is the last thing on my mind[though it has to be light enough to transport by plane], and crew protection is a must have.

I think that makes a good MBT
