In this question:
Forming a "concave" with your army
We get a nice explanation of why we want to form arcs with our armies. What I'm wondering is how to actually do it, in terms of commands. Two ways I know of:
- Moving your whole army perpendicular from the opposing forces until they form an arc, then hitting 'Hold Position'.
- Boxing and spreading units manually.
Is there an easier way, maybe with multiple control groups and/or hold/patrol commands? How are the top players forming their arcs?
The reason I use "Hold" to form my arcs is because a line is formed when you run your units as far as their sizes combined. If you simply 'Move' to the position, you will bunch up into a ball. I guess I can try 'Stop' for this instead like has been suggested, but what I'm really hoping for is more along the lines of Budda's answer of using 3 control groups (maybe even pre-split with N marauders, N marines, and N/4 medivacs). I'm going to leave the question open for a little while longer just to make sure we're not missing anything.
Sadly, it appears that positioning units manually is the best arc forming method. I still find myself using patrol to send units north, shift-move them just a few steps south of the north rally point, and then shift-move to where I want to go (further north in this example) to get a better arc (YMMV). I chose the more general answer even though I may have liked the other answer better because I think it will better fit users coming in from Google. Thanks again.
