Humm, as in the "crouch" mode that you can use, as a player?
Well, there's this syntax, something like:
Unit setbehaviour "Combat";
Unit setUnitPos "UP";
Unit switchMove "CrouchToCombat"
Can't quite remember the actual switchMove name
If you mean some for me unknown animation used in OFP:R, I have no clue what-so-ever.
It doesn't hurt to repeat and elaborate your question in your message, to keep us from having to guess. Hrmm.
Wolfrug out.
