CoD: Modern Warfare Remastered kicks off St. Patrick's Day event

Activision has officially announced the launch of "Operation: Shamrock & Awe", an event to celebrate St. Patrick's Day. It's starting today and running through to 12:01AM PDT on April 3, 2017. During this event, there will be free weekly supply drops, a new map, 2 unlockable weapon camos, new playable character and more.

The free supply drops will be available only for 1 week, so if you don't claim them in time, they're gone for good. There will also be supply drops scattered throughout the map to collect.
The new free map is called "Daybreak". It's a modified version of the map "Downpour" and (because it's St. Patrick's Day) it features a lot of green decor. It'll be free but only available during Operation: Shamrock & Awe.

As for the new playable character, here's the official description:

"As part of Operation: Shamrock & Awe, three new themed collections will provide you with St. Patrick’s Day theme reticles, camos, calling cards, and emblems. Each set will also include a bounty for completing the set: assemble the “Luck” collection to earn a new character, “Leprechaun” rewards you with a Shillelagh melee weapon, and “Pot o’ Gold” gives you a unique calling card worth fightin’ for.
But that’s not all. If you craft or unlock all three themed collections, you’ll also unlock Darren “Graves” Cosgrave as a playable character for the first time ever!"

Darren “Graves” Cosgrave will be unlockable only during this event but if you manage to unlock him, you get to keep him.
