What are the pros and cons of both of these jobs? Is it easier to get promoted doing one over the other? What are the main uses for both in Iraq?

An M1 is a tank. You will spend your whole career in the damn thing.

The linebacker is just a Bradley tricked out (less seats) for Air Defense Artillery. Bradley's are the tough armored personnel carriers. They are ballistic rated at 30mm and have a 25mm cannon, TOW launcher and .762 Machine gun.

The vast majority of Bradley's are found in the Infantry though some ADA units and Scouts use them. Here in Europe all of the linebackers went away and the crews were involuntarily re classed in they were under E7.

The Bradley (loaded with Infantry dismounts) is the most lethal vehicle in the world! But you must enlist Infantry and get a mechanized duty station just to have a shot at being a crew member.

Jon1std is right but in iraq u will do your job or u will be dismounted with 11b's or with us but if u do the M1 thing its a good chance u wont get in a tank unit! we got tankers who drive our strykers and not M1A1's or M1A2's sep tanks( the new ones) so its like a flip of a coin and points for both are really low all combat arms mos's have low points.

Thanks for the replies. They were really helpful.
