Mjölnir

Mjölnir is Nora Valkyrie's secondary weapon.

It is classified as a Multi-Role Collapsible Launcher (MRCL) with three different modes.

Description
Mjölnir can shift into a rocket launcher, a mortar, and a smaller form for storage.

In its storage form, Mjölnir is carried on the right side of Nora's back, being held in place by an electromagnet.

Rocket Launcher
Mjölnir's first form resembles an extensively modified M4 MAWS with a longer barrel and a more sophisticated targeting computer. The longer barrel supports having multiple rounds in the chamber, allowing Nora to fire multiple times before needing to reload.

Mjölnir's handle is situated slightly above Nora's right shoulder. When she pulls upward on it, Mjölnir shifts into its rocket launcher form. Nora then disengages the electromagnet and pulls it onto her shoulder, ready to fire.

Mortar
When needed, Nora can further shift Mjölnir into its mortar form. With a twist of the barrel, a bipod mount and base plate spring out of the weapon, allowing for it to be mounted onto the ground.

In its mortar form, Mjölnir can make use of many different types of ammunition, such as illumination rounds, smoke rounds, and high explosive rounds (ground and airburst).
