I always assumed it was saying +1 to your command rating; a one-point bonus in other words. Plusses and minuses get thrown around loosely in the rules, so context is always the best guide to what they meant. Surely in this case they wanted the cav to be impetuous, therefore it makes sense that it would be a one-point bonus to the command rating or a one-point subtraction to the dice (which is a bonus).
Could be wrong, but that’s what makes the most sense to me.
Thanks, those are helpful suggestions. On the arid and scruffy Peninsular battlefields where my games take place, I’m wondering if I can’t get around a lot of the awkwardness of woods by treating them simply as rough ground, but with the ability to make targets unclear? That would still bar cavalry and artillery and only the unclear target aspect would need a house rule.

Much to think about. Thanks, guys.
