My first game of head to head MEG last night, as opposed to a couple of solo games, and I had an issue arising with charging.
In my case I had charged (stupidly , but that's another matter) with a SUG cavalry unit to get rid of an opposing foot SUG. It evaded behind a Cavalry TUG directly behind it (which had not had any combat losses) which was in charge reach, and we couldn't see any mechanism to stop my SUG hitting the TUG and effectively dying, apart from the rule that a SUG can't charge a TUG (not within one base of breaking) in the open. We played they charged in and died....
My searching of the forum would indicate from a couple of years ago that there was to be an amendment to the clarries such that the SUG could have stopped one base width short, but I don't see that in the latest clarries document.
Re-reading the rules I have a more general query for both TUG's and SUG's about charges and evaders in that do you have to charge the full charge distance if you are not a forced charger? I can't see anything to say you can limit the length of your charge, but that does mean if I want to drive off some skirmishers, or even some missile armed cavalry my unit is always in danger of having to hit any unit that is behind them, unless I have previously done in a prior turn some fancy footwork to only just be in charge reach of the first unit?
