Strafing attacks, and how to master them, was quintessencial in Dons Essays. You need to protect your big stack with an umbrella of dead zones.
The best way to do a strafe attack is with a few infantry as fodder, and a strong airforce to do the killing. You need to predict, by doing some math, how many kills the defender is likely do do, and then adjust your infantry fodder to cover the kills, and your heavy hitters to kill exactly the numbers of casualties you want to inflict on the defender.
Strafe attacks can be done in 3 ways.
Hit and run, kill the big enemy stack but let one defender survive, so you can retreat your surviving units.
Hit and run used in a tricky way to give your infantry an extra free move. Attack space B with a huge infantry stack from space A and one unit from space C, make sure one defender survive, and retreat all your surviving units into space C. One free move for the slow infantry. This is a legal move, you can retreat all your units to a friendly space from which some of the combat moves startet, even if it dont feel right, or fair.
Take the territory with one surviving infantry. This is the best way, you gain the income and your unit will block enemy Blitzes. If a territory is occupied by one enemy infantry, then you attack with one or two infantry and some fighters.
Now, some poor players complain about this, and want to play Low Luck, or make house rules that take the risk out of strafe attacks. That is not cool, man. The game is designed this way to make it fun and challenging. It is better to learn to play the game, in the gamey way it was supposed to be played, than to house rule out the luck.
Hope this was helpful, man. Now, gimme a like  :-D
