I knew there was a lot of them
Now that they are in the OOBs, they essentially have to stay there I am afraid. They may be used in scenarios, or scenarios in user campaigns and removal is likely to result in problems.
Now we have the OOBSs under our control again, we can be more selective on what goes in (or not). But as you say - 2 of these or so would have done, if any really. Scenario designers can always make up "special farces" types from regular infantry units, as these things are really only of use in such, not in normal games.
