Why Was the Arma 2 Reinforcements CD Key So Important?

To understand the value of this CD key, you need to look at the state of Arma 2 before the era of seamless Steam integration. Initially, the game and its expansions were sold as physical retail copies—DVDs in cardboard boxes. Inside each box was a printed CD key (also called a product code or serial number).

The Reinforcements key was uniquely powerful because it provided:

  1. The British Armed Forces (BAF) Pack: Added the British Army with L85A2 rifles, Challenger 2 tanks, Merlin and Lynx helicopters, and a 5-mission campaign set in Afghanistan (Operation Crimson Lance).
  2. The Private Military Company (PMC) Pack: Added a modern, high-tech mercenary faction with civilian-style SUVs, Blackwater-style tactical gear, and a gritty 8-mission campaign focused on convoy ambushes and corporate espionage.
  3. Standalone Capability: Crucially, Arma 2: Reinforcements could run without the original Arma 2. However, to access the full Arma 2: Combined Operations (which includes the original campaign and assets), you needed both keys.

For the thriving DayZ mod community (the original survival mod that started it all), the Reinforcements key was also desirable because some modded servers used BAF or PMC weapons and vehicles.

"Invalid Product Code"

This can mean three things: you typed it incorrectly (try retyping, not copy-pasting, to avoid hidden spaces), the key is for a different region (e.g., Russian key on a US account), or the key has been corrupted/revoked.

If you have a Steam key:

  1. Activate via Games > Activate a Product on Steam.
  2. It will install as a separate entry in your library: "ARMA 2: BAF" and "ARMA 2: PMC."
  3. Launch Operation Arrowhead. In the main menu, go to Expansions. Enable BAF and PMC. Restart the game. Done.

Do You Still Need an Arma 2 Reinforcements CD Key in 2024?

Short answer: No, if you buy the Arma 2: Complete Collection on Steam during a sale (often 70-80% off, bringing it to under $10), you will automatically get BAF and PMC without needing a separate key.
