What does the "check" command do in Frozen Synapse?

I've noticed that there is an order you can give to your units called "Check".

However, the tutorial doesn't explain what it is and I can't really tell what it does.

What is this for, and when should I use it?


Solution 1:

I believe this forces your unit to look in that specific direction without necessarily aiming down the sight or decreasing his movement speed. It's a momentary glance so he will engage targets in that direction, then continue on hustling at full speed.
