Squeezing through

[PoorOldSpike]

Yes you can certainly try to squeeze through a longish or crooked gap, but its by no means certain the tank will go through!
So be prepared a lot of the time to see your tank refuse to do it and auto-plot its own course to take it the long way round like they did in the "No" pics above.
Remember, the pics are actual live tests and we can see with our own eyes them refusing to go through the "No's".
Personally when playing CM I never waste time fiddling about trying to thread tanks through longish and crooked gaps because I know it'll often be a waste of time trying, so I only go through the easy short gaps as in the "Yes" pics..
