Do you mean the damage ** ? If you do, it's 'hidden' in the FAQs section of the Game Guide:

What are those " ** "'s I see when I hit an AFV?

When a tank is hit and a penetration occurs it does not always cause an outright "kill". Occasionally, depending on the shell size/armour thickness ratio and the survivability rating of that vehicle, you may notice hit messages ending in ***. These are not new, they have always been in SP2 but it was not widely known that this indicates that damage is occurring to a vehicle. We have reworked the code to give more of these damage results under certain conditions. If you see these when your tank is hit you are taking critical damage and/or lost crewmen which affects the number of shots available and overall vehicle/crew performance. Damaging hits can also remove weapons, immobilise the vehicle and so forth (note that unlike the original SP series games, bringing up the information screen for an enemy AFV will not show you that, for example, the main gun has been destroyed for that vehicle!).
