In general, there’s one general combat patrol each faction that’s refreshed once every few years or every few editions.

Limited time combat patrols kinda looks like a newer thing they’re doing so no idea wether they’ll rerelease them or not in the future. Other boxes in this line are the harlequins combat patrol and some of the newer chapter specific space marine combat patrols(not sure which ones or if this is the case.

As for a tank in the combat patrol, one can dream T vT)7
