Full Metal Pony

Angel watched the figure silently, his watchful eyes never falling off track. The unicorn, he had made it out to be, was looking around confused, looking for something. It wasn't until the unicorn turned her face towards the fire did Angel see who he was looking at. He rolled onto his stomach and propped himself up to walk over to the figure. She looked up, and recognized the snow-white unicorn walking towards him. "How did you find us?" he whispered, walking her away from the others, sound asleep. "I followed your tracks. Kind of easy to spot them." She said. They both looked to the woods, keeping an eye out. "Does Celestia know you've left the castle?" Angel asked a hint of worry in his voice. "Oh, she sent me with something for you." she said, and pulled an envelope out of her satchel. Angel took it and began reading.
"Angel Kidd,
You know I hold you in high regards for saving the lives of my squad back in the castle, but we have a graver issue right now. Your time in the Vanguard Coalition will prove vital. Even though you and your group were the renegades of my personal guard, you still have ste skills that you were trained with, and that is something that very well may save us. I need you, along with every pony else to get to the castle right away, for I fear Equestria’s safety.

Princess Celestia.
P.S: I am having some Pegasi drop off some top secret weapons we were working on to take targets out from further away, make good use of them"
Angel read it over once more to make sure he understood. "Well it says we are getting something that can kill a changeling from a great distance... wonder what it is..." he said, turning around to get some sleep." Oh, Colgate. Pick a spot you like and get some rest, they should recognize you from the meeting in the castle." Angel said, looking over his shoulder. He curled in his spot by the fire, and gazed at the stars above him as he drifted away.
They were woken up abruptly, a voice shouting them awake. "Twilight Sparkle, By order of Princess Celestia, we have brought you out new ranged weapons." He went on, but Twilight ignored most of it and got up. "Now, we were also instructed to give you steps to put them on, fire them, and such. Rainbow wanted to try them first. It was a two pony job, one to set the device on her back, get the wings through the openings, and attach the loading device. "Now, this will fold down, and whatever is in the circle is what the bolt will hopefully hit. Standing still you have a better chance of hitting something. Now, take this pressure bit, and get it in your teeth. Bite down when you are ready to fire." The instructor commanded, and places a case of bolts in the loading system. a catch was released, and one bolt rolled down a line into a loader, where it was locked into the crossbow and ready for firing. Rainbow had the target dummy in her sights, and focused to still her body, and bit the pressure plate. Her body jolted with the force of the bolt being shot from the crossbow. The dummy was decimated, hay from inside was strewn everywhere. "Twilight, while every pony else gets set up, come here. I got this letter from Celestia and think that you should know." he explained, letting her read the letter. "Well, I’ll tell the girls that we're moving out as soon as we can." she said, and walked over to them. After they had all had a turn getting used to the weapon, they started packing up for the journey to the palace, not knowing what awaited them.
