Because not all Languages are created equal, the US military has devised a means in which to grade language levels based on their difficulty to learn. Their breakdown is as follows:
- 95 for a Category I language (Dutch, French, Italian, Portuguese, and Spanish)
- 100 for a Category II language (German)
- 105 for a Category III language (Belorussian, Czech, Greek, Hebrew, Persian, Polish, Russian, Serbian/Croatian, Slovak, Tagalog [Filipino], Thai, Turkish, Ukrainian, and Vietnamese)
- 110 for a Category IV language (Arabic, Chinese, Japanese, and Korean)
According to the military, languages like Chinese, Korean, and Arabic are much harder than French, Italian, and Portuguese. This author would not disagree with them. Languages like Chinese, Korean, Japanese, and Arabic do not use the greek alphabet. Therefore language learners of these types have to learn a whole new alphabet and in most cases have to learn new sounds.
