I recently finished an excellent three-session run of the zine with four players, and this is my review:

 "The Five Techniques is equal parts raucous, brooding, tense and politically astute. With a brash and colourful but GM-friendly layout and studiously helpful supporting materials, the vibrant radicalism of 70s Punk clashes and fuses with the simmering violence of the Troubles and something old and sinister beneath."
