Made this a good while ago. Strictly speaking, not military equipment, but still some imaginative alternate ammunition.
Used by professional thieves and other criminals in my fantasy setting. Guns are also available, but loud and ill-suited for firing specialised ammo, hence the enduring popularity of bows and crossbows. I've made sure most of these arrows and bolts would actually work in real life and be light enough to fly well. Some of these are true offensive ammunition, others are purely tools and contraptions on an arrowshaft. Most of the arrowheads contain smaller but sturdy clockwork mechanisms or are designed to behave in certain ways on most impacts. Only one variant uses alchemical substances by default in order to work. The arrowheads in the explosive set are obviously some of the heaviest and can't fly far. The mundane broadheads and bodkins obviously come in more shape variations than just the two shown here, but you get the idea.
Quick overview of what is what:
Broadhead - normally used mainly as a hunting arrowhead; good against soft tissues and therefore unarmoured or lightly armoured opponents
Bodkin - an arrowhead that's mostly seen military use; fairly effective at penetrating thicker armours, including mail, but incapable of beating plate
Flathead/Blunthead - cheapo arrowhead that's incapable of sticking into targets; can be used to hit switches or daze enemies instead
Ruckus - decoy clockwork arrowhead, activated on impact by the button at the front; the trigger sets off wind-up clockwork rattles, bells and whistles built into the arrowhead
Knockout - incapacitating clockwork arrowhead (as the name implies); after the button sets off the trigger, knockout gas, or sleeping gas, etc., is pushed out of the gas cylinder inside through small openings
Dousing - dousing as in "putting out an open fire"; glass arrowheads of different sizes, filled with water or special extinguishing liquid, have multiple possible uses (main one being enhancing shadows at night)
Ignition - mechanical or alchemical arrowhead with an explosive and/or igniting effect; the mechanical variant has a striking trigger which ignites the gunpowder with a spark, the alchemical variant has a simpler trigger which intentionally destabilises the alchemical mixture stored inside
Before you ask: I intend to finish a second sheet, with the rest of the ammo. It's long overdo. The second sheet will mostly show similarly specialised darts for dart pistols, and various bolts and missiles used as grappling hooks.
