In the medieval period, soldiers were basically supposed to carry hyoro by themselves, but at the front, they took along only a few days worth of it and got konida to carry the rest, because the term was unpredictable and the heavy stuff could prevent their military action.
中世においては、兵粮などは兵士達の自己携帯が原則であったが、実戦においては期間が不明でかつ長期分の携帯は軍事行動の妨げになるだけであったため、数日分だけを携帯させてそれ以上の分は小荷駄に輸送させた。
