Disrupt is the action described in this step because early in a vessel-on-vessel encounter the aim is to interrupt the aggressor’s ability to maneuver or threaten, creating space and shifting the dynamics without escalating to higher-force options. Disruption focuses on breaking the opponent’s pattern, trajectory, or plan so you can safely de-escalate or disengage. Why this fits Step 2: it sets the stage for safety by interrupting the threat and reducing immediacy, rather than relying on a show of presence, attempting to disable the other vessel, or firing warning shots. Command presence is about establishing authority and deterrence; that's typically an earlier or separate emphasis. Disabling would be a more forceful option reserved for later goals if disruption fails or the threat persists. Warning shots/LA-51 are explicit escalation tactics and not the immediate Step 2 action.
