Current British Infantrymen get 26 weeks of training before they can be deployed, Gukhas 38 weeks. According to the BBC Private Tomkinson (18th Battalion, Manchester Regiment) "went through 13 months of good, sound training" before deploying to France in October 1915. By the time conscription came in basic training was three months plus weeks or months on specialist training with deployment to transit camps in France for further training before deployment. Time wise, it seems, the process was not too disimilar. However weapons and tactics were totally different in WW1 from a modern "conventional" as opposed to a-symetric conflict. The WW1 tactics were unproven by any previous experience. Great play was made of artillery - indeed it caused the majority of caualties during the war. Machine guns and trench systems protected by barbed wire ran from the North Sea to Switzerland after the initial war of manouvre. Reconnaisence and air support were rudimentary. The use of cavalry stymied. Communications and transport difficult except where railways, good roads and telegraph systems existed. So how could an army trained and organised to today's standards adapt and succeed? Don't think about inventions such as the tank etc. but purely on whether infantrymen, artillarymen and airman with period kit could get the job done better than it was done. After all the German Spring 18 offensive used better trained troops and tactics to almost succeed!
