Your "division" could modify an old Chaddy End favourite. It would go along the lines of:
"We are the Chaddy Enders (C.E.W.E. division),
We are the Chaddy Enders (C.E.W.E. division),
We are the Chaddy Enders (C.E.W.E. division),
We are the Chaddy Enders (C.E.W.E. division),
We are the Chaddy Enders (C.E.W.E. division)... etc."
Hope this helps.
