Note. To the best of my knowledge this is not based on any existing Fallout Equestria storyline, nor does it follow any particular plot in Fallout 4. This is just the narrative that popped into my head as I worked on this piece.
Sweetie Drops fired a burst from her submachine gun then she ducked back behind the column of worn, bullet riddled, pre-war concrete. She caught a brief glimpse of one member of the Black Hoof gang crumple to the ground as several of her 9x19mm rounds found their mark.
The other members of the Black Hoof expressed their disapproval at Sweetie's actions by peppering the concrete column and ground around her with another volley of assorted gunfire. Chunks of column and the concrete floor went flying and a cloud of concrete dust now swirled around the area. Mingled amongst the roar of gunfire was sound of whizzing bullets and pinging ricocheting projectiles. The mare sighed and then muttered to herself.
Waiting for a pause in the gangsters fire Sweetie once again leaned back around the column again and fired another burst at her assailants. She dove back behind cover as her gun ran dry. Smoke rose from her weapon as she dropped the empty 40rd magazine from the weapon and pulled fresh magazine from her web gear. With her gun reloaded she grumbled.
Intensive firing on an enemy position is an ammo consuming activity.
Seen them run out in combat right in the middle of their charge on my position as I waited......reduced to a Browning HiPower and a broken M16A1.
