NEP Brass likes the heavy stuff, but once in a while the Design Bureau can slip past a real versatile design like the Prowler. The trick is to give it some kind of bullshit designation like "Rapid Assault AFV" and then stuff as much power plant in it while they're not looking. A nice low profile, operates well in urban environments.
The Prowler balances speed and armament well. Open up the engine on a straightaway and the speed is there, perfect for flanking, even if the boost is only for short bursts.
