Accolades are awards given in-game in Call of Duty: Modern Warfare 2 multiplayer, awarded for completing various tasks or doing the most or best of something. They are awarded after completion of a game. The "top three" show up in your post-game screen, but you can get more than just 3 per game.

Trivia

 * The accolade "Hard Boiled" may be a reference to the 1992 movie also called "Hard Boiled" starring Chow Yun-Fat which features many gun fights involving pistols, it may also be a reference to a comic of the same name in which the protagonist wielded a pair of pistols.
 * To get "Warming Up" you need to finish a match without getting any other accolades. The easiest way to do this is in a private match, as shown here: http://www.youtube.com/watch?v=ARPI_q8ucqQ
 * A good way to get the "Hot Potato" accolade is to throw a grenade without cooking it, then pick it up and throw it again.
 * Accolades are the only thing that can be earned offline or in private matches and be carried over to online multiplayer profiles.
 * It is mathematically impossible to get the MVP accolade without also getting the Juggernaut and The Feared accolades.
 * Some accolades such as "Fewest deaths" or "Highest kill-death ratio" cannot normally be obtained if the player entered near the end of the match. The game will not award the "Fewest deaths" accolade to a player that entered near the end of a Team Deathmatch and got 1 kill 0 deaths, even if he has the fewest deaths. Sometimes this does not apply and the player is still given the accolade, but this is very rare.
 * The "Most HQ destroyed" accolade is classified as better than the "Most HQ captured" accolade, even though the one who destroys the most HQs is very likely to be in the losing team, while the one who captures the most probably is in the winning team (and has contributed to the win).
 * In Demolition, where there usually are several players that destroyed one target, the "Most targets destroyed" accolade (the one classified as "best" for Demolition matches) is given randomly to one of them.
 * Accolades do NOT award experience.
 * The "None Spared" accolade seems to be the easiest to obtain, with many players who haven't even reached level 70 having it well over 100 times.
