RogueTech: How does a squad of four Urbanmechs qualify to be in the Solaris assault mech championship?

I get that the unit technically ticks off all the right boxes with regards to tonnage and pilot classifications, but it honestly looks out of place, and it's easy to beat since its mobility is so low.

What do you guys think?

Edit: It might be funny, but to me, duct-taping four Urbanmechs together doesn't make them an assault mech. It's still just four light mechs stapled to one another.
