"Before the October 7, 2023 attacks, the total size of Hamas’s military wing (the Izz ad-Din al-Qassam Brigades) was estimated by the Israel Defense Forces (IDF) and intelligence agencies to be between 25,000 and 30,000 fighters, with some intelligence assessments placing the upper limit as high as 40,000. This army was organized into five regional brigades and 24 battalions."
"Hamas's military force prior to October 7, 2023, was roughly 3 to 4.5 times larger than the United States military when measured as a percentage of their respective total populations."

Anyway, IDF as ≈170k active duty personnel and 465k reservists[1]. Literally a different order of magnitude. Add to it the vast different of resources, access to an air force and nuclear weapons and it become even more clearer that there is no comparison possible.
(And comparing personnel count to the USA is laughable as it is vastly different military type. Both a fighter jet pilot and a foot soldier count as one personnel, but it's neither the same force projection nor the same investment of civilians working for the war machine).
