After a few months of drawing this and it's mini drawos it's finally done. This sheet shows some Indian soldiers from the Mangy Mesozoic from 15-45. Infantry guns evolved from the martini-henry z to the ZA/ZAW and finally to the ZAWA (single shot to multi-shot weapons.) Vehicles without turrets to having spontoons to full blown turrets. Planes becoming faster and heavier armed. Helicopters evolving. Ships/Boats becoming bigger and becoming ironclads, dreadnoughts, and dreadnought destroyers. Submarines evolving external engines to help in flight and becoming faster in land and on sea.

The soldiers have changed greatly since the beginning of Napoleon's army to India in 45.
A change with all soldiers was greater firepower through the ZAWA, autocannons and bigger cannons.
Another change with all was better armor such as gambeson and fluff with vehicles even though it's not shown here.
Another universal change was better information processers and optics with better and more scope and a side mounted computer/flashlight for handguns and vehicles being able to see better and farther.
The final universal change was matter generators and gun mounted ammo loaders becoming better, so better and more complex materials and items being built faster and faster and even portable matter generators.

Ammo loaders and matter generators break The Law of Conservation of Matter and The Law of Thermodynamics since they can create energy and matter with absurd effect.

Vehicles can also evolve while living and are almost impossible to truly kill and biologicals are ageless.
