M29 Grizzly

The M29 "Grizzly" Infantry Fighting Vehicle was the standard "battle taxi" of Systems Alliance Marines for 20 years. However, while excellent in long-term planetary campaigns, the Grizzly's bulk and weight made it unsuitable for rapid deployment across the Alliance's expanding sphere of influence. As such, this led to the development of the M35 Mako, effectively phasing the Grizzly out.
