This is as good as it gets. This IL is ridiculously hard, do a wrong move and the soldiers will spot you. Make no mistake, the setup is as important as the line. Actually aligning D-Horse for the perfect start is insane, just try to aim for the tree to the left at 0:13. Also, spam the dash button and the action button so you get on D-Horse and sprint at the same time.
