Good morning,
this situation has presented itself a couple times when fighting with my targaryen and someone pointed me to some inconsistencies on the way i was playing. i've been pointed that if you don't have any characters with military icons at that point you can't initiate a military chalenge with them becouse you need a character with that icon in order to initiate a chalenge. that has been established and accepted.
the issue comes at another point. when you have indeed a character with a military crest on the table you can initiate the chalenge, then you should kneel any character you want to attack with (and here's the real issue) do you need to kneel anyone or you can wait till the next player action window and play horseback archers basicaly making him attack alone or he can only be played as a boost to a military chalenge? (preaty much as a +3 str to a military chalenge making him much less interesting than making him able to attack alone).
hopefully you can shed some light on this issue.
