Tattoos are part of some natives' culture and you can see from the malaysiakini photo that these tattoos usually signify major events in the Iban's life.
Therefore the authorities should check if there is indeed a practice to discriminate against such youths who want to join Malaysia's Armed Forces.
According to the malaysiakini article there is Nothing wrong with 'tattoo' soldiers and yet some of these youths were denied the chance to serve their country.
I agree that "what matters is their loyalty and bravery in the defence of their country and not the tattoos on their bodies."
