Ground attack for fighter career questions

[oho]

How can I generate more ground attack missions for Me109 fighter squadron?

Do you also generate attacks on moving columns on roads sometimes?

In the squadron configuration directory each squadron has a set of roles and weights.  Me109 squadrons are 90 fighter and 10 ground attack.  You can find your squadron and increase the ground attack weight to generate more ground attack missions for your squadron.  You can also just scrub missions until you get a ground attack.
