The training which in ordinary times would form the course of study for years now has to be crammed into a few months, and it stands to reason that much which is essential remain unlearnt. I have generally found that the best way to train young officers in minor tactics is by giving them as realistically as possible little problems to solve, and afterwards in the presence of their comrades to discuss their proposed dispositions and then to tell them clearly what they ought to have done, giving reasons for every step taken.
