Frequently Asked Questions

How did the 405th get its name?
In 2003, Bungie presented a real-time demo of Halo 2 at E3. This demo includes the only time the 405th is directly mentioned. In the demo a cut-scene is shown in which Master Chief is being flown into New Mombasa. As he flies in he asks “Who was first contact?” and Sergeant Major Johnson responds “405th out of Diego Garcia. But don’t expect a big welcome. Covenant wiped most of them out before they hit the ground.” Unfortunately, the line regarding the 405th was cut from the final version of the cutscene. No other mention of the 405th is made although one has to assume that the troops, including Corporal Perez who greets Master Chief after he lands in New Mambaso, are a remnant of the 405th.

Classifieds Guidelines


    2. Because this is such an important point, let us say it again in a slightly different way: PLEASE DO NOT MAKE BUYING, SELLING, INTEREST POSTS/THREADS OUTSIDE OF THE CLASSIFIEDS FORUMS.
    3. Only FULL MEMBERS are allowed to SELL in the community and only in the appropriate CLASSIFIEDS forum. See below for more information on Member Types.
    4. Any CLASSIFIEDS forum thread that has not had a post in 60 days may be removed.
    5. Members using the CLASSIFIEDS forums do so at their own risk. All transactions are the responsibility of the buyer and seller.
    6. A seller is only allowed to bump their thread once every 24 hours.
    7. Selling items for, or on behalf of someone else is considered shilling and is not permitted.
    8. Selling for or promoting services, products or sites of banned members or known re-casters is not permitted.
    9. Auctions (other than MARKETPLACE "FA" threads), charity auctions, sales mentioning a charity or raffles of any kind are not permitted.
    10. Price "bashing" is not allowed. If you don't like the price of an item move along without comment. If you are interested in buying an item for less than the displayed price, contact the seller ONLY if they have specified that they are willing to accept offers.
    11. A seller may NOT request PayPal payment be made as a "gift" (this means choosing "I'm sending money to family or friends" from the Send Money page in PayPal). A seller may NOT request buyer pay for PayPal fees. If a seller chooses to accept PayPal, all fees should be calculated into the sales price.
    12. The sale or trade of live firearms is strictly prohibited on the site. The sale or trade of deactivated firearms is permitted only if the item in question has been rendered completely non-functional as described under the applicable laws of BOTH the buyer and seller's home country/state/province.
    13. The decision to sell to a particular member is solely at the discretion of the seller. A seller may not sell to a member for any reason or no (stated) reason at all. Negative feedback left to a seller because they did not want to sell to you will be removed.


There are two member types in our community. ALL registered members can BUY by posting in an existing CLASSIFIEDS forums thread, or by starting a WANT TO BUY thread.

    1. New Member – a member who has been registered for less than 90 days OR has less than 50* posts.
      This member CAN NOT SELL or ADVERTISE in the community.
    2. Full Access Member – a member who has been registered for at least 90 days AND has 50* or more posts.
      This member CAN SELL and ADVERTISE in the community.
      *Posts in the CLASSIFIEDS forums do not count toward a member's total post count.
