Matetranslate gives "armoured discovery utility vehicle"
and for Voiture de Prise de Contact gives "car pickup contact" which sounds like a vehicle designed to patrol red light districts. Either that or an early telegraph based Uber App.
Interesting, but I'm wondering about the 3LMG's. are they part of the vehicle's equipment, and remain inside usually, but not fired without passengers? Its' the only way I can see 3 LMG's being used. Would need some note about a SCA, PCA, or RCA 2fire 8 range LMG if carrying passengers.
