Ok Greg reinforcements this is a bit hit and miss
I think the idea is that a friendly army within the red zone that has an arrow to your army will reinforce you on the battlemap but this doesn't always happen however the AI always seem to manage it!
The only way to be sure you armies will reinforce each other it to have them right next to each other on the campaign map one behind the other side by side sometimes doesn't work
So if you come right up behind Jen's army with your army you will be able to assist her in the battle if you leave big gap it is not a certainty you will reinforce her
Saying that this is how it seems to work in single player not played co-op yet
