I wrote a desciption of the Gersan army uniform: 

Jacket and trousers are both dark brown wool/cotton blend. The jacket extends to the crotch area with four pockets across the front; two high at breast level and two low at waist level. Gold buttons adorn the pockets and four larger gold buttons provide closure to the jacket at the center of the body. The jacket has epaulets on both shoulders displaying an olive drab board containing the appropriate rank insignia. The edge of the board is lined in a red pin stripe. A red pin stripe identifies the soldier as infantry. Other colors would be used for other jobs like Armor, field artillery or Engineers. The Gersan soldier wears black leather boots ending just below the knee and a black 2” wide leather belt at the waist. The load bearing equipment is made of black leather straps and canvas pouches. The standard headgear is a dark brown garrison cap; the thin rectangular shaped cap that spreads over the head and is tapered to a point at the top. The second is an olive-green steel pot intended as protection against shrapnel. For colder weather, a pair of black leather gloves and a heavier olive green field jacket.
