Yeah that's right, Dassault made the MWS for all M2000 series (C, D, N, -5F, and others) but French Air Force use it only on the D variant, M2000C is able to carry it but I've never seen any C with it, and as far as I know, the Escadron de chasse 1/2 "cigogne" (Fighter Squadron 1/2 "storks") have few MWS in stock for their M2000-5F but doesn't use it.
