Using an Army Promotion Points Calculator to tally up your points haul is a great alternative to wading through complicated regulations, like Army Regulation 600-8-19 (Enlisted Promotions and Reductions).
Although the Army Regulations (AR) can certainly provide you with the important information you need, you can get lost in the bureaucracy and red tape. Let's face it, AR's are not light reading and are published to ensure there is no room for debate or question. Unfortunately, this makes them highly technical in format and language and can be difficult to interpret. Somehow, root canals can seem like a more pleasant experience! Okay, maybe I exaggerate a bit, but I'm sure you understand where I'm coming from.
