may also give air cover. As in the European game the combat group then makes a defence roll (surviving CAP added to the defence strength), after which any surviving non-aborted attacking air may now attack the enemy combat group. Naval Air Squadrons - but not army air factors - may target individual fast carriers, which may themselves make a separate defence roll prior to being attacked. It will be recalled that a fast carrier has 2 or 3 factors - if each factor is "destroyed" or damaged twice by the attack, the ship as a whole is deemed "sunk", while if each factor is either "destroyed" or damaged once, the ship as a whole is deemed to be "damaged" and must leave the combat (attacking NAS must return to the aircraft carrier from which they took off, or be lost if she has been sunk, although those flying CAP may land at any carrier or friendly land base (at the cost of inverting)). Any other result (i.e. at least one carrier factor remaining in pristine condition) is deemed to be repaired at sea and the carrier begins the next round of combat with all factors once again intact. The difference between the two players' search rolls is the "surprise" result enjoyed by the player with the higher search result for that round of combat. High levels of surprise can be catastrophic, with CAP or defence rolls delayed until after the air attack or disallowed altogether, or all damage being lethal - this is what makes a disaster like the Battle of Midway possible. A second round of air attacks may now ensue, starting with a fresh search roll. After two rounds of air attack, naval surface combat may commence, with each side adding in a new combat group with each round (once engaged in surface combat, a combat group need no longer be "searched" for!). Surface combat is actually and perhaps unrealistically rare, and not the way to sink fast carriers as they are deemed to be "screened" by any ordinary naval factors in their combat group. There are some hard-to-remember rule anomalies - army air factors (if they survive counterair) are added to the defence strength of a naval base, but this is not true if they are giving air cover to a naval force - the opposite is true of naval air squadrons flying CAP. Some of these
