These chaps are either FV (grey wolf) or CV (lapin sota) and are rifle panzerfaust. They are therefore perfect for anti tank up close. The two main use I've found for them are these - objective holding, ambushing.
Objective holding, this is the easiest explanation. If I'm against a tank force sitting these guys on an objective is a great deterrent, I will normally mix them with a regular infantry platoon, able to add to defensive fire, but also not be hit in the first charge into combat.
Ambushing is far more fun. The platoon is small enough you can fit them easily in many terrain areas, and suddenly around woods and buildings it's a complete no go area! Even with recon it will limit your opponents manoeuvrability. If they do stray too close you can pop out and if lucky assault units from cover!
Anyway I hope you like the little update - until next time.
