In Tom Clancy’s Rainbow Six Siege, the Preparation Phase plays a pivotal role in shaping the dynamics of a match. It serves as the penultimate step prior to the Action Phase, and its efficient execution can significantly influence the outcome of the round for both teams—the Defenders and the Attackers.

For Defenders:
The Preparation Phase is crucial for defenders as it allows them to solidify their positions and set up their defenses around the objective. Here are the key aspects of their preparation:

1. Fortification of Objective Sites: Defenders have the opportunity to reinforce walls and hatches, barricade doors and windows, and strategically place gadgets. This fortification helps in controlling sightlines and entry points, making it challenging for attackers.

2. Strategic Gadget Deployment: Assigning gadgets like barbed wire, Jäger’s active defense systems, or Kapkan’s traps is vital. The placement of these gadgets should be thoughtful—certain walls may be left unreinforced to create potential bait for attackers or to conserve crucial resources.

3. Time Management: Defenders must efficiently balance the time spent on reinforcement versus gadget placement. Ideally, they would leave door barricading towards the end of the phase to avoid teammates accidentally breaching their own defenses during setup.

4. Creating Misleading Defenses: A common strategy involves intentionally leaving certain paths less fortified to confuse attackers about where the main objective is and divert their attention elsewhere. This psychological tactic can be advantageous during conflict.

For Attackers:
The Preparation Phase primarily focuses on information gathering, making it a crucial phase for Attackers to set up for their assault:

1. Scouting the Map: Attackers deploy remote drones to canvass the area, locate the objective, and observe enemy placements. This reconnaissance is integral for understanding the defenders’ strategy and planning the best possible routes and tactics.

2. Gathering Intelligence: The information attained during this phase regarding enemy gadgets, traps, and potential vulnerabilities can help attackers formulate a tactical plan that maximizes their chances of success during the Action Phase.

3. Planning and Coordination: Drones can also reveal the positioning of enemies and their defenses, enabling attackers to coordinate effectively. This facilitates collaboration among team members to decide on various engagement strategies.

Crucially, Attackers do not place gadgets or barricades during the Preparation Phase; their entire focus is on reconnaissance to achieve a tactical edge.

Conclusion:
Ultimately, the Preparation Phase serves as a crucial strategic window for both teams. While defenders work quickly to establish a formidable defense and mislead opponents, attackers execute a critical reconnaissance mission to gather intel and formulate attack strategies. Both roles require swift action and effective time management to ensure success in the following Action Phase, making this period a defining moment in each round of Rainbow Six Siege.
