The SAF trained several Malay officers, before the SAF introduced "Malay" platoons with 2 SIR, 3 SIR, 4 SIR.
SAF has been trying to induct Malay officers since just after it's inception.
Malay teachers were enticed with commission, some straight to Captains and Majors, but the effort mostly failed. Teachers have no inclination for fighting.
After that the ranks had to be filled up with Chinese, which ended up making SAF a racist organisation, stuffed full with helicopter chobolan ahbengs.
