Assignments

Assignments are objective-based tasks featured in Battlefield 3 that reward players with weapons, camos, or dog-tags upon completion. Every assignment that doesn't require time spent on their respective DLCs can be completed on maps outside of them. Certain assignments require others to be completed before any progress can be made.

The release of Battlefield Premium, Close Quarters, Armored Kill, Aftermath, and End Game have expanded 65 more assignments. Assignments do not necessarily require players to play as the implied class to make progress toward that assignment.

Assignment List
There are currently 75 available assignments (10 Back to Karkand, Close Quarters and Aftermath, 5 Armored Kill and End Game and 35 Premium) to be completed in Battlefield 3.

Battlefield Premium
Unlike other Assignments, once completed, Battlefield Premium assignments unlock unique dogtags, and camos exclusive to the service.

Back to Karkand
Assignments were introduced with the release of Battlefield 3: Back to Karkand.

Close Quarters
Close Quarters introduced ten new assignments and were revealed through the June Maintenance of Battlelog.

Armored Kill
Armored Kill introduced five new assignments which were revealed on September 3rd, 2012. Since the pack contains no new weapons, the assignments unlock vehicle specializations and unlike most assignments in other expansions, these can only be completed on the respective maps.

Aftermath
Aftermath introduced ten new assignments that were revealed on November 20th, 2012 through maintenance on Battlelog. These pertain to the expansion's new weapon, the XBOW and dog-tags.

End Game
End Game introduced five new assignments which were revealed on March 1st, 2013 Battlefield Blog post. While all five assignments pertain to unlocking dog tags, one allows the player to unlock the M1911 S-TAC, a variant of the M1911 with both a Tactical Flashlight and a Suppressor attached.

Trivia

 * The Professional Russian assignment most likely refers to the popular YouTube uploader, FPS Russia, who jokes that he is a professional Russian on multiple occasions, even having a shirt available to purchase with the phrase.
 * Whether it is a coincidence or not, FPS Russia had an episode featuring the L85A2 just after Back to Karkand was released.
 * The Scarred Veteran assignment takes a noticeably longer time to complete for many players due to the need to play a total of four hours on two specific maps. The map-specific challenges are unique to the all-kits weapons (but only for the Back to Karkand expansion pack).
 * If you complete an assignment in the top row (or first per class), you get 2500 bonus points. If you complete one on the bottom row (second per class), you get 5000 bonus points.
 * The weapons featured in the Battlefield Premium assignments (F2000, PKP Pecheneg, L96, SCAR-H, L85A2, LSAT, SKS, MTAR-21) are the weapons that are allowed to equip camouflage. The assignments unlock a second camo pattern, with the first provided as part of the Premium package.
 * The filler text in the Assignment images on Battlelog is taken from Battlefield Premium marketing material, and is completely unrelated to the weapons or items pictured.
