Does the single-player campaign unlock anything for multiplayer?

Will I get any weapons or something usable in multiplayer if I complete Singleplayer? Does Difficulty matter? (Battlefield 3 did unlock something in multiplayer. Or at least co-op did. If I remember clearly.)

It's not like I'm not interested in the story or it's that hard to headshot everyone through the map, but it can be annoying on harder levels. I'm trying to decide if it's worth plaything through the harder difficulties, so knowing what I might get is good to know.

There are 6 multiplayer weapons you can unlock through the campaign. You can check them under Assignments -> Single Player Assignments. They are as follows:

TOMBSTONE ACTUAL (CAMPAIGN) AWARD REQUIREMENTS Complete Baku REWARD M412 REX FANG OF THE UNDERWORLD (CAMPAIGN) AWARD REQUIREMENTS Complete Kunlun Mountains REWARD SHANK A TRAPPED WOLF WILL (CAMPAIGN) AWARD REQUIREMENTS Complete Tashgar REWARD MACHETE TO VALHALLA (CAMPAIGN) AWARD REQUIREMENTS Make the final choice REWARD QBZ-95-1 PEACE MAKER (CAMPAIGN) AWARD REQUIREMENTS Make the final choice REWARD P90 FINAL DUTY (CAMPAIGN) AWARD REQUIREMENTS Make the final choice REWARD M249 

* SPOILER *

The last 3 require you to play the final mission 3 times, choosing a different ending each play through: kill Hannah, let the Valkyrie be destroyed, or kill Irish.
