This is the General Astrodynamics Argus 10-31A APC. It is designated as a personnel carrier and fire support vehicle that has seating for six infantry and one pilot.
Above you'll see an exclusive version of the Argus from tJY: showing off the Imperial colours and insignia. The first shot below is of the Argus in Colonial colours and insignia.
The concept for this APC was done by Beltash, modeling by Chemeleon, and skinning by Trinity. Below are shots of the Argus in flight (photoshopped), view with the landing gear down, and a rear / interior shot.
