2 volks and 2 puppchens is all it takes to roll over it.
Approach with volks(preferably, but not mandatory with shrecks) from one side(preferably through yellow cover at least), sneak up 2 puppchens, volks draw fire and poke it, puppchens rip it apart and either force brace or its dead within next 9 seconds.
Its not like its schwerer which can take crapload of punishment without holding fire and fights off med armor
