Hi All, I only discovered OPR the other day and have to say I love the idea! I was one of those that went out and bought a good amount of 40k stuff and never used it! I was always reading the rules then leaving it a while and getting put off trying to learn the rules again.
So far I've played two games of OPR and have my kids playing it - so thanks, that's a big win!
I have a question, it's probably a really dumb one but I'm going to ask in any case. How do you define a unit exactly? For movement there is a rule about staying within 2" and also a different system for wounds, i.e groups don't role on the wound table.
So if I had a unit with 3 Battle Brothers for example and if they take wounds they would then get removed. However - if the same 3 battle brothers were counted as 3 separate units then there is a chance they just end up stunned and not removed from the game.
Am I missing something or is this something decided at the start of the game?
In our game I just decided that up to three of the same type of unit (3 x Battle Brothers or 3 x TAO grunts) had to be considered a unit (or a squad if you like)
Yeah, this is set up at the beginning of the game. So when you deploy your unit of three, you place them within 2" of each other, they stay together for the whole game, and you remove models till there's only one left, which uses the wound table.
Far as I can tell, the rules as written don't allow for deploying them separately, but I guess there's no reason you couldn't house-rule it as such if you wanted.
On the army lists it says in square brackets how many models are in a unit. So for example battle brothers come in units of  model, whilst goblins come in units of  model. You can't simply put multiple models within 2" of each other and call them a unit.
