We’ve included rules for the most common method used to deploy here. This is often referred to as the ‘Standard Deployment Method’ and is the method used in the majority of Warhammer 40,000 missions. You should feel free to devise other methods for your own game if you prefer. For example, some players like to place a screen across the centre of the table so that their armies can deploy in secret; others draw a map showing where they plan to deploy their units, and so on.
Write down the details of the models that make up your army, which units belong to which Detachments, which Detachment is your Primary Detachment, and which model is the army’s Warlord. This written record is known as your army’s force roster, and you must keep it to hand while you play the game. To keep things fair, you must always allow your opponent to read your force roster before a game if they wish to do so.
In the above cases, it's pretty explicitly clear that you should be honest with your opponent what units go where.Combined Reserve Units
During deployment, when deciding which units are kept as Reserves, you must specify if any of the Independent Characters in Reserve are joining a unit, in which case they must arrive together. Similarly, you must specify if any units in Reserve are embarked upon any Transport vehicles in Reserve, in which case they will arrive together. In either case, when making a Reserve Roll (see below) for a combined unit, roll a single dice for the unit and/or its Independent Character/Transport vehicle.
