I was pleasantly surprised that Brunei is not part of the Saudi alliance while sad that Malaysia, Pakistan, Bangladesh and Maldives are. As expected Indonesia is not part of the alliance.
In fact Gurkhas were even deployed by the British Army to fight and neutralize Indonesian paramilitary forces during the Konfrontasi. They (Gurkhas) have had a presence in Borneo ever since the British Army's counteroffensive to reclaim Borneo from the Imperial Japanese Army back in 1945.
