meltagun

Etsul heard Jorgens cursing over the vox. 'Throne's sakes, not again! Ghansk, flank sweep. M'baru, check–'
Shimmering columns of energy stabbed into Ogre's right flank. Time seemed to stretch as furious heat haze danced before Etsul's eyes and a white-hot glow grew from the right flank of Jorgens' tank, before the moment snapped back and the Demolisher exploded with such force the shock wave almost stalled Tread in the breach. Shrapnel rattled from their hull, and Etsul felt her gorge rise at the thought of her comrades' remains vaporised in amongst the shards.
'You dreggin' heretic scum!' yelled Chalenboor. Her heavy bolter thumped, riddling a band of Spinebacks armed with meltaguns. Etsul realised belatedly that the traitors must have emerged from a priest house to Ogre's right while everyone was preoccupied with the threat from the left. It had taken only a single salvo from their tank-killing weapons to accomplish what platoons of heretics had failed to achieve.
