I have been unable to change a group's speed in the Scenario Editor. I've tried different delta's (1 sec, 1 hour, 1 hour before the time limit in case the timing is in terms of time left in the scenario) without any success. I realize I must be doing something wrong but ? Would someone suggest how I can change a group's speed at the beginning of the game (e.g., group ADU has a max speed setting in the Battleset Scenario I am hoping tp modify - I would like it to be at creep speed as soon as possible to the opening of the game). Thank you.

Try this:

 

1) Plot course for Group (if there isn't one already entered)

2) Select Edit and the Previous button to move back to Point zero.

3) Enter speed at this point

 

Should work fine, now.

When you first click the 'Course' button to set a course for a Group, you need to check (put an 'X' in) the little window that says 'Set New Legs'.

 

Then click the 'Speed' button (its not in the Course pop-up window but rather off to your left) to enter an initial speed.
