Drones, it seems, are all the rage and many of the systems were unmanned. This leads to large, uncluttered flat surfaces devoid of vision slots and other paraphernalia which might normally aid crew members. Indeed, there were some vehicles which were manned, but piloted via video systems so the on-board driver doesn't have to be seated at the front with a windshield. Freed from such constraints such carriers look more like smooth, angular torpedoes.
Most astonishingly some of the equipment seems to come straight out of James Cameron's Aliens. There were fully automated tripod-mounted machine guns, much like those used in the famous scene cut from the theatrical release. The unit can scan for targets using both normal light and infra red. There was also a portable banks of screens able to show the head-cam, gun-cam and vital functions of team members.
It's game over, man!
