Many players do not understand when to use Air Power. An Airfield requires that an Engineering Brigade, Motor Pool, and Artillery Brigade be built first. That’s a fairly significant investment regardless of whether you are playing a 1v1 game or a team game. In addition a single Airfield will cost between $360 and $400, depending on the country. On top of that, each bomber run will cost $150 per raid. That is some serious $$$ to be throwing around.
Due to the high initial cost of purchasing the buildings necessary for an Airfield, coupled with the cost of the Airfield itself, and the additional cost of each raid, it is not suggested that players only attempt to get an Airfield early on in a game. Air Power should be reserved for the very end of the game, after a player has at least 12, if not 18 Regiments on the map.
Once an Airfield is available, a player must decide ‘what’ to bomb. There are 4 available targets to bomb: main Corps HQ, other HQs (Infantry, Mechanized, and Armor), Airfields, and Enemy Regiments.
In order to ensure victory, attack items in this order:
o Airfields
o Corps HQ
o Other HQs (Infantry, Mechanized, Armor)
o Enemy Regiments
Airfields should always be the number one target if you can find them. After all, you would much rather be bombing your opponent than have him bomb you. After their Airfields are down, take out their Corps HQ. Without a Corps HQ, your opponent can not build other HQs or another Airfield. Once the Main Corps HQ is destroyed, begin taking out their other HQs. Once enough of them are destroyed, their economy will be in ruins. Finally, go after their remaining Regiments (if there are any at this time).
It is possible to use Air Power to break through an enemy line by attacking their Regiments first. If properly timed with a ground attack, an air campaign can be devastating to enemy forces. However, with this approach, timing is everything, and a properly time air/ground attack is extremely difficult execute successfully. Thus, this approach should only be utilized by the most skillful of players.
