Thanks for contacting World Warfare Support.
World Warfare focuses more on real war experience, which results in a relatively slow tempo of the game. This slow tempo affects not only the move speed of troops but also constructing, producing, training, etc.
Because of this, the key of winning is not your operating skills or micro-managing skills, but your macro-managing planning and strategic thinking of the whole war.
There are a few ways to speed up troops. Tanks can move at double speed under Force March mode. Blitzkrieg tactic can grant 40% speed boost to all your and your allies' troops. Transport planes will help you to transport ground troops faster.
