ok u run towards the gdi base without beeing seen (offcourse )
lets say there are 4 mediums defending the base because of a destroyed AGT by flame rushes
one stealth has to stand agains the sidewalls and bend over (crouch)
then the other one must jump atop of the other stealth's back and jump over the wall,then he is behind the barracks and the rest is up to u

(keep in mind that the one with the nuke has to jump over the walls and not the other one)

it helpt me very much

if u have other tactics about my favourite map just say it
