Scrapbus and Flak

No idea sorry. I'll bet someone in here knows though!

I wanted to know the level and combine that with the data of camp and outpost spawning levels so I know what limit my offense and defense levels should be on my support bases. I plan to have an air army on every support base and Flak just simply ruin it. Its for farming crates...

Flak towers start appearing in defenses of level 18 outposts.

I have a question about these units:
At what level does each unit appear in camps and outposts? I've seen the Scrapbus somewhere at around outpost level 12, but not to other situations. Can anyone give me the levels?

Like you suggest, the situation determines that.
Strategic factors.
