从公元前600年左右起，欧亚大草原上的人们开始掌握骑术。到公元前400年左右，与农耕民族交界的北方游牧部落将骑马与射箭相结合，形成了一支马背上的强大军事力量。骑兵出现后，农耕民族与游牧部落之间的贸易活动和文化交流日益兴盛。无论是赵武灵王的“胡服骑射”还是秦汉长城的修筑，都与来自欧亚草原的骑兵密切相关。骑兵尤其是重装骑兵的出现革新了战争形态。文献记载的“甲骑具装”，为将士和马匹都披上厚重铠甲，可如同坦克一般冲锋陷阵，所向披靡。湾漳壁画墓出土的甲骑具装俑（见图）便是这一兵种的真实写照。近年来，在邺城正南门朱明门外的护城河中，意外发现了一具保存相对完好的“甲骑具装”铁铠实物。当时能够编入军队的这类兵种数量或许还相对有限，也存在一些马身未披铠甲的骑兵。

Super Steady video has been upgraded to a 360-degree horizontal lock. This camera mode uses the S26’s gyroscopes to maintain a consistent horizon even as you rush to chase a pet or family member while recording, or to capture snowboarding buddies. (There’s always a snowboarding example when a company mentions horizontal lock.) It’s nice to see a feature we’re used to finding on gimbals and action cams built into an unashamedly mainstream phone like the S26.
