Answer: Tanks and military-grade planes
Explanation: Imperialism was about almost everywhere in Europe at the time and around that time most European countries had territories in Africa which lead to constant fighting for the land there. What this lead to was intense fights between nations by them creating proxy wars (militias/Rebel groups) to fight against each other which were being supplied by that country that wants more land for them self. With that it lead to Archduke assassination which lead countries to declare wars on one country which then would mean they would declare war on multiple countries in realty because countries would ally each other and the domino effect went down hill from that. So Archduke assassination was just really a "reason" to fight with another nation for more land (resources).
A warrior relied on his herd to provide him with staple foods of milk and meat; hide for their bowstrings, shoes and armor; dried dung (dried poop) to be used as fuel for his fire (poop is flammable); hair for rope, battle standards, musical instruments and helmet decorations; milk also used for shamanistic ceremonies to ensure victory; and for hunting and entertainment that often served as military training. If he died in battle, a horse would sometimes be sacrificed with him to provide a mount for the afterlife.
