Some soldiers in the Guard were awarded a fourth chevron (more than 30 years of service), but they were very few. In 1807, the hat was replaced by the shako, which was made of black felt, chevron on the side and visor, a brass diamond shaped plate stamped with the Imperial eagle over the unit's regimental number, white cords, and brass chin scales.

From 1793, the uniforms of the demi-brigade of the line infantry wore the blue "National Uniform" that was to be worn by all soldiers. Other than that the information is quite good which gives an introduction with an excellent map and has some information.The uniform of the Horse artillery of the line was made of a hussar-style blue coat with red braids, red cuffs and brass buttons.

Their brass buttons were gilt, they had epaulettes according to their rank, and, on duty, they had a gilt gorget with a silver badge, generally a crowned eagle. We cannot accept people who have them as "friends" on Facebook for instance, because they harass then our own friends with hundreds of spams. However, for a long time, line infantry were a mix of the new blue coats worn by the National Guard and the white uniforms of seasoned veterans from the old Royal army. The hat, a black felt bicorne, was the standard infantry headdress at some of Napoleon's greatest battles.The uniform comprised pewter buttons, black boots, a brass helmet with a brass crest supporting a woolen crest named chenille ( caterpillar, in French), a sealskin turban, black leather visor, brass chin scales and red epaulettes for elite companies.
