As much as Aura hated it, the Wolf had a point, the Heavy Bolter on the Valkyrie would do more to stem the coming tide that her hotshot. So, under his covering fire, she picked up from her current bit of cover, an Ork missing most of it's skull, and ran for the Valkyrie at a dead sprint. Arriving quickly, she slung the hotshot then jumped, getting herself into the crashed vehicle as fast as possible. She then strapped in to the door gunner's seat and checked the weapon's ammo feed. It was good to go, no shells damaged and the weapon itself was also fine. Aura gave a smirk beneath her carapace armor, and opened up.
In the way that only one who usually had to fight without them could, Aura adored heavy weapons. Her regiment, being a drop regiment, was often sent in without many of them after all. So, when she did have the chance to use a heavy bolter, such as now, she made sure to make the absolute most of it. So, once she first squeezed the trigger and adjusted to what recoil the weapon's mount didn't absorb, she promptly began scything down Orks as they emerged. She prioritized targets with the biggest guns, and as anyone of the Rangers would tell you, that was the most important thing to do with a Bolter of any kind. However, since scything down those specific Orks didn't take long, she then swapped to simply unloading into the biggest clusters, grinning as Mass-reactive explosive rounds shattered Ork mobs.
