One of the primary benefits of the M32 chassis was it's versatility, allowing multiple variants to be produced. With the baseline model only able to hold six infantry (due to the space taken up by the turret), the Army still needed a platform that could take over the role of simple battle taxi, replacing the rather old M113 and M1126 Stryker armored personnel carriers. Out of this need, the M32-ICV (infantry carrier vehicle) was born. Due to the obvious elimination of the turret, the -ICV model is equipped with a CROWS, which offers a variety of armament options from 7.62mm or 12.7mm machine guns, to 40mm grenade launchers.
Much closer to the Boxer-esque origins of the design methinks.
Apologies for the poor picture quality, took them outside during a rainstorm. :3
