ارتش بسیاری از کشورها نسبتاً کوچک هستند و برخی از کشورها کمتر از 100000 پرسنل نظامی دارند. برای مثال، آفریقای جنوبی و آرژانتین به ترتیب دارای ارتشی با 74000 و 72100 پرسنل نظامی هستند. حتی ارتش‌های کوچک‌تری را می‌توان در کشورهایی مانند اسلواکی یافت که دارای ارتشی متشکل از 17950 پرسنل نظامی است.
شایان ذکر است که اندازه ارتش یک کشور تنها عامل تعیین کننده توانایی نظامی آن نیست. عواملی مانند آموزش، فناوری و تاکتیک نیز نقش بسزایی دارند. علاوه بر این، برخی از کشورها ممکن است به سایر شاخه‌های نیروهای مسلح خود، مانند نیروی دریایی یا نیروی هوایی، برای ارائه توانایی نظامی متکی باشند. به طور کلی، اندازه ارتش یک کشور تنها یک تکه از پازل در مورد قدرت نظامی است. در جدول زیر تعداد پرسنل ارتش کشورهای مختلف جهان را مشاهده می کنید:
