Of the two approaches to hobby games today, one is best defined as the realism-simulation school and the other as the game school. AD&D is assuredly an adherent of the latter school. It does not stress any realism (in the author's opinon an absurd effort at best considering the topic!). It does little to attempt to simulate anything either. (AD&D) is first and foremost a game for the fun and enjoyment of those who seek the use of imagination and creativity.... In all cases, however, the reader should understand that AD&D is designed to be an amusing and diverting pastime, something which an fill a few hours or consume endless days, as the participants desire, but in no case something to be taken too seriously. For fun, excitement and captivating fantasy, AD&D is unsurpassed.As a realistic simulation of things from the realm of make-believe or even as a reflection of midieval or ancient warfare or culture or society, it can be deemed only a dismal failure. Readers who seek the later must search elsewhere. - Gary Gygax. 1e DMG.
