== A few more comments/suggestions (not comprehensive) == 

 *Lede is completely uncited, so should be carefully checked to ensure each statement is elsewhere in the text. I'd suggest hidden comments to say where. 
 *Commanders: 
 **When did French's term start? Why was he replaced? 
 **"conduct during the war" or "conduct of the war""? 
 *Organisantion: 
 **consider "any conflict" or "any external conflict"? 
 **link first use of Guards, infantry, cavalry regiment, division, brigade, battalion, how big are these units? 
 **relate 3s6d/week to the modern equivalent 
 *Recruitment and conscription 
 **not just men, women (esp nurses), boys (some of 14) volunteered 
 *Doctrine 
 ** the quotation "In every respect the Expeditionary Force in 1914 was incomparably the best trained, best organized, and best equipped British Army which ever went forth to war." is attributed in Beckett & Simpson p.38 to J.E. Edmonds' Military Operations, France and Belgium, 1914, Volume I, pp.10-11, HMSO London (1925) should be verified and properly attributed 
 *Artillery tactics 
 **link first use of creeping barrage, indirect fire 
 *Communications 
 **link first use of dispatch, trench wireless set, flags 
 *Life in the trenches 
 **lice and rats didn't cause the diseases, they carried them. 
 *Gas helmet

 * that's all for now, perhaps more later.
