here are the first 2.

Delta`s role is much like Barricade form TF 2007 movie.
he is like a scout ant, saw the mobina and call for the big guns.
utilize his uzi to put the hurt on the innocents.

Beta the biggest of the group. he is like
lognut with aa IQ on repairing.
using his vetical take off plane to see the target and his pickup to intercept.
