I'm looking to pick up the models for this sectorial before they become too hard to find and wanted to make sure I wasn't failing hard on my searches for moblots or zouaves. I was able to find one each in the MRRF starter which was easy enough, but after that things seemed to dry up. I did find sapper options for both and the zouave from the starter in a single blister as well as a moblot with rifle/light shotgun. Is this all there is for official models or were there box sets like the briscards and loup-garou?
Only the Starter Set, Equipe Mirage, Briscards and Loup-Garou had box sets. Everything else was found in blisters. Every unit found in the army had at least one or more blisters. If you are searching for a place to get them and don't mind paying for shipping, you can still find them over here. https://www.waylandgames.co.uk/782-ariadna#/
I also caught the MRRF bug late. I had a scattered bunch of units before but no cohesive force for the Sectorial, and have been remedying that. I have gotten a bunch of stuff off of Amazon and eBay for reasonably cheap, including the Loup-Garou and Briscards boxes.
Off the top of my head, the Zouave has a DEP/assault pistol sculpt in both starter and blister, and then two blister sapper sculpts: one for sniper, one for HMG. Similarly, off the top of my head, Zouave has the starter box rifle/LSG, a blister with shoulder-mounted panzerfaust, and the sapper HMG blister too.
Moblots had 4 minis. The female rifle/lsg in the starter, the female panzerfaust (who was an arm swap of the starter one), a male with rifle/lsg in a reloading pose and the sapper hmg. If you can find them the old vet Kazak hmg and the vet Kazak rifle in the old starter box fit in very well with the Moblots, gives you more weapon variation and enough unique minis for a full core.
