Plus the many Arab volunteers of the 'Free Arabia' Legion ('Freies Arabien'), whose members countries of origin ranged from Syria, Saudi Arabia, Egypt, Trans-Jordan, Palestine, Lebanon, Morocco, Tunisia, Algeria, Iran and Iraq, plus quite a few obscure others (like Senussi and Tuaregs and various desert Arab tribes and peoples). The numbers for the Free Arabia Legion were 20,000+.
In the closing days of the war, about 100 Arab soldiers under Major I.G. Schacht, in the 25th Parachute Regiment of the 9th Parachute Division, would even fight in defense of Berlin, right at its doorstep with their German comrades. Major Schacht wrote of their enormous courage, praising his Arab men for saving his life on numerous occasions.
In a 1925 personal letter he wrote:
Germany also had many Axis partners who fought beside its courageous soldiers. Countries like: Italy, Japan, Romania, Hungary, Slovakia, Bulgaria, Yugoslavia, Croatia, Finland ('co-belligerent'), Serbia, San Marino, Iraq, Albania and Thailand (who became a formal ally of Japan on 1-25-42).
Many Axis allies were to be found in occupied or liberated countries as well. Countries like Norway (under Vidkun Quisling's regime), Russia (under General Vlassov and others), Denmark, Ukraine, Greece, Macedonia, Lithuania, Latvia, Georgia, Azerbaijani... the list goes on and on.
There were also large numbers of supporters in unlikely places like America and Britain. The American Bund party rallies were so large they looked like they were held in Germany! And of course, many countries of South America were friends to the Axis countries, and even had National Socialist parties of their own.

[Above: This is a map produced by the SS (Germanische Leitstelle, Amtsgruppe D of the SS-Hauptamt), one of the last documents produced by the SS foreign volunteers recruitment office. The map has various errors and shields that hadn't been physically produced yet, like the Swedish and Slovenian shields, for example, but it is still very interesting. Click to enlarge!]
