Basic ballistic weapons, used to create basic military weapons such as seeker sniper rifles, rifles, pistols, SMGs or shotguns. All rifle sized variants have a large charging handle located on the left hand side of weapon's receiver and use detachable box magazines located behind the upper accessory rail directly above the weapon's pistol grip. Most use cartridge based ammunition as shell casings can clearly seen being ejected from the weapon whilst firing, the shotgun and the revolver being notable exceptions to this.
- Contrary to previous games and popular belief, ballistic weapons crafted from Military Engines fares extremely well against Necromorphs, even with body shots. Their high damage output, manageable accuracy combined with large magazine capacity makes them one of the most efficient weapons when combating Necromorphs, if not the best.
- Military Engines can be fitted with the most number of tips in the game. Their number of DLC tips is also the largest.
- Despite Classic mode removing any non-Classic weapon from play, the player is still given a Bullpup Rifle (Miltary Engine + Rail Accelerator tip) at the beginning of the Prologue.
- This (these if playing on co-op) is the only non-Classic weapon available to the player throughout Classic mode, not counting DLCs. It is also removed from the player's inventory upon completion of the Prologue chapter.
- The Bullpup Rifle (Rail Accelerator-tipped Military Engine) is one of the most common weapons seen in the hands of NPCs, mostly John Carver, who uses the same rifle throughout the game, and most Circle soldiers.
- If playing on Co-op, the Carver player immediately receives a Bullpup Rifle at the beginning of the game, which gives him a slight edge over the Isaac player.
- An unupgraded Precision-tipped Military Engine offers the damage output and stopping power of a charged Contact Beam shot.
- A Rail Accelerator-tipped Military Engine is called a bullpup rifle. A weapon is a "bullpup" when the magazine and loading systems are placed behind the trigger group. This is strange, as ALL Heavy-Framed Military Engines are configured the same way (magazine behind trigger), regardless of tip.
- The position of the magazine well and firing system of Military Engines, however, is positioned directly on top of the trigger group, making them not quite in a bullpup configuration, technically speaking.
