However, this post concerns their two Arms and Uniforms titles  on the Napoleonic Wars: Volume one covers the French army, including Napoleon and his staff, and everything else except the various formations of the Imperial Guard. Then it goes on to cover the British, Prussian and Spanish armies. Volume two starts with the Imperial Guard, and then moves on to 'Allies of the French' (from Confederation of the Rhine to Italy and Naples, etc.), and the Swedish, Austrian and Russian armies. Unsurprisingly, it's the French army that gets the fullest treatment. 
I absolutely love these two books, as they were a powerful part of my early interest in the period. Consequently the Funckens also have a special place on the nostalgia map of my soul!
 There are numerous illustrations of equipment, badges, flags, etc. Mostly in colour.
 The Arms and Uniforms series covered everything from the ancients, through medieval, right up to the two World Wars.
 As a result of this fuller coverage I've always had a soft spot for certain more obscure branches of the French military machine, from the artillery train, or the medics, to the Eclaireurs. Often based purely on the aesthetics/colour schemes of their uniforms!
