Well the British soldiers wore a green khaki colour uniform, with the regiment they wer in (e.g. Manchester) on a badge on their shoulder. They hat different hats too. The officers nd ppl had green normal hats (not sure what they're called!) , but when they wer going into battle it was green tin hats that looked a bit like bowler hats but just metal. Hope it helps!
I think they wore like ragged khaki and wool jackets. They had worn shoes and sometimes no blankets. They had to carry heavy packs on their backs, with food, and water, and canteens.
I don't know about American, or any other soilders. Yet, Russian soilders were highly unequipped- 1 in 3 soilders didn't even have a gun, despite the colossal taxes placed apon the Russian population, leading to the discontented attitude of the nation. Soilders were freezing, some didn't even have shoes, in trenches stuffed with corpses and freezing water; leading to illness and an increase in diseases; and blatentley a decrease in hygeine. The French army, began world war one, on HORSES- riding bravely into shards of German machine gun fire, unsuprisingly the majority of the French horseman were massacred, thus leading to the changed army and the equipent of suitable guns and clothing.
