I have a mixed BG of 6 bases with 4 HF and 2 LF bases



what the rule for 90 ° turns, 180 ° turns contractions and expansion rules?
can i reorganize them as i want at each change of formation?

Turning 180 the original front rank becomes the new front rank. Turning 90 I've never thought about and never read a rule on.

Rulebook, page 45:

When a mixed battle group turns, its new front edge must, if possible, consist of the same base types as the old front edge. Bases are simply relocated to achieve this.
