As a stealth unit I can safely call BS on this.
From FWGY you have 2 guards right at the fence to the lower base, 3 more just inside the fence, and a pat with 2 dogs that can see through stealth.
Then at top of the hill, at the entrance to the entry tower before you head up into the upper half of the horde base, there are 3 more guards outside, plus a pat inside the tower there. then as you go up the last hill into the upper base…
You have another pat, then at the fence to the upper base you have 2 more guards, and ANOTHER pat.
And then, after ALL that, if you go up into the right hand tower, the very first guard on the top of the tower will see you and start hitting you before you even get to the top floor.
It isn’t tagged as a stealth seeing unit but it can see you regardless.
That and there is an annoying glitch where the horde guards can sometimes see you from stealth and will shoot you even at the lower parts of the base.
Getting in to the Alliance base is a joke in comparison.
And an edit to add: the alliance bunkers are far enough apart that you only take fire from the guards from one bunker at a time.
But the Horde towers are so close together that you have all the archers from BOTH towers shooting you when you engage.
