G.I. Joe: A Real American Hero # 127 1992 VF/NM

G.I. Joe: A Real American Hero # 127 published by Marvel Comics in August 1992, features a major confrontation between the Joes and Cobra Commander over an advanced military weapon. 

"Playing with the Big Boys!"

The story centers on a powerful new technology called the Rapid Pulse Electron Beam (RPEB), which can strike targets across a hemisphere by bouncing beams off satellites. 

• Cobra's Infiltration: Cobra Commander successfully hacks into the RPEB's control system via a telephone switching station in New Jersey.
• The Joes' Response: Original G.I. Joe team leader Joseph Colton discovers the breach and alerts Duke and Stalker. The Drug Elimination Force (DEF) team is redirected from their mission against the "Headman" and his drug shipments to assist.
• Cobra's Devious Victory: Cobra Commander shoots down the Joes' Tomahawk and temporarily takes control of the laser system. He uses it to destroy a cargo ship carrying Headman's drug shipment—not out of altruism, but to manipulate the Joes and settle his own scores before escaping undetected into New York City. 

• Baroness Dossier: This issue includes a detailed character bio and origin story for the Baroness, featuring artwork by the legendary George Pérez.
• Character Updates: It marks the first appearance of Duke, Stalker, and Wild Bill in their new (3rd and 2nd) uniform iterations.
• Villain Performance: Critics often highlight this issue as a high point for Cobra Commander, showing him winning through devious and highly intelligent independent planning.
