Ambush and Leadership modifier

[Tycho]

My Internet search capabilities are lacking today..

Not pinned while stacked with a MMC - *must* (instead of *may*) you use your leadership modifier when rolling for ambush? It looks like the A11.4 paragraph and table don't give you the option not to, but we weren't sure.
I'm thinking I should have pulled my mighty 6+1 off the line earlier 8O
