Mechanics

What it shows. Your objectives and the main places, dangerous zones and enemy Compounds, useful buildings and caches (Locations of interest: stations, caches, towers, compounds), where the radiation is spreading (Radiation storm and Time Remaining), and you, nearby enemies and your squad's pings. From it you can ping, cancel your current Op and read your DMZ Orders ^[1].

Grid. Letters run west to east and numbers north to south; D7, for example, is Imjin Farmland. Every key's description gives its grid square (Keys and locked loot rooms).

Rest of the HUD. Time Remaining; Objectives (Story Missions, Dynamic Ops and Side Ops on the left, DMZ Orders on the right); a 1–360° compass naming the POI you are in; the area's Threat Level under it (Threat Escalation system); the Hostiles Kill Count (Hostiles Kill Count and Marked for Death); a squad panel with each Operator's health, plates, DMZ Cash, gas mask and parachute; the Backpack menu; the Ping Wheel (Proximity chat).
