More broadly, this reform helped usher in Cromwell's New Model Army. This reorganized force, designed for unity and efficiency, incorporated several practices recognizable in modern armies. In addition to a professional officer corps promoted on merit, it replaced the sometimes bulky local units with nationally controlled regiments, standardized training protocols, and ensured regular salary payments to the troops. This army soon turned the war in favour of Parliament, decisively beating the Royalist forces at the battle of Naseby on 14 June 1645.
