To miss a target from low-level is almost impossible? At least if you believe the modifiers I have on the to-hit tables.
As it is now you don't have individual targets. For example, if your target is an airfield, you will bomb all targets there in an "area bombing" type of attack. The landing strip, hangars, gun positions and planes, and everything you can find on an airfield. Individual targets must be more difficut to hit, but I don't know a good way to decide what your target will be and how that will affect your group's results.
To attack a single target, a tank or ship for instance, you can dive bomb, glide bomb, skip bomb or drop a torpedo and you will know if you hit it or not and what the damage is.
Para Frags/Demos will increase your chance of hitting the target even further.
Rockets will destroy targets on the ground, but how many or how much in %? If you follow with bombs will you have a negative modifier on the to-hit table or a positive modifier on the accuracy table?
And if you strafe with machine guns, how will that affect your bomb run and the result?
I have been thinking about using TZ-4a for both medium/high and low-level missions, but I am also working on a separate to-hit for low-level missions.
