Since English Is not my native language, i think i have misread the times about Cover. In the wiki reference It data that must cover at least 1/3 of his height. So is not possibile to gain cover while leasing from a verticale corner of a Building?
Exactly: Partial Cover Partial Cover partially blocks the attacker's vision of his target. Requirements The target of the BS Attack must be in base contact with a piece of scenery. For a piece of scenery to be considered a valid Cover, it must conceal at least a third of the target. This means that it must have a height that is equal to or higher than one third of the target's height, and must also cover at least the equivalent of one third of its base. When in doubt, check the Silhouette (S) attribute of the target and its Silhouette Template to see the measurements of that minimum height and width. When drawing LoF, the attacker must be able to see at least a part of his target the size of its head, approximately 3mm by 3mm (the size of the black squares on Silhouette Templates). Effects The trooper that declared a BS Attack must apply a -3 MOD to its BS Attribute. The target of the BS Attack can apply a +3 MOD to its ARM/BTS Attribute in any possible subsequent ARM/BTS Rolls. Red is my emphasis.
