At the start of a game, Turn 1 impulse 1, is your turn mode and side slip considered fulfilled so that you can do either move for the first hex you move?

Yes.

That's what i said, but a recent opponent said no, at least for side slipping.

The opponent is sadly wrong; you and Scoutdad are right

Even at weapon status 1 (SFB) all turning/slip modes are fulfilled at the beginning of a scenario unless the brief says other wise.

This is all covered in (8B3) of the Rev 5 rules.

Oh...I only looked in the movement section. Didn't think to look way back there. Thanks.
