Decisions, decisions! You can get to Base Cochise via two main methods: * Walking up to the front gate and knocking (entry will require use of the Picklock skill or Demolitions (TNT, Plastic explosive, LAW rocket, Sabot rocket, or RPG-7), plus Secpass B (found in the Inner Sanctum of the Guardian Citadel). * Flying the Helicopter from the Inner Sanctum of the Guardian Citadel (requires Helicopter pilot skill - trainable at Sleeper Base Level 3 in the simulator). Note: repairing the simulator will require the use of a Rom board, which you can loot from one of the groups you fight just outside the main gate of Base Cochise. (So, I guess they want you to take a stab at cracking the outer defenses before you helicopter in?).
