This is a very vague and exceedingly difficult question to answer. Comparisons of various armed are extremely difficult to make, especially in the case of your question which spans 4 years of development. Comparisons of armed forces are also notorious places for awful and relatively uninformed answers, answers which rarely consider the vast amount of nuances in command, hardware, leadership and countless other variables. Generally speaking, the best questions to ask in history are specific ones. In the case of your question, instead of asking about the entire military, try a question about armor doctrine, or a comparison of strategy.
