To set the record straight: According to Mindef, "Servicemen are to salute officers who are senior in rank. In the course of official duties, National Cadet Corps Officers should also be saluted. Police Officers and military officers from foreign armies are to be accorded the same compliments paid to SAF Officers. The salute can be executed while in any military attire, with or without headdress." NCC students will greet SAF personnel no matter what rank. NCC teacher officers will greet SAF personnel as a matter of courtesy although not stated in rules, and return compliments when paid.
The aim of the NCC? There is no operational role, although they are trained to BMT+ standard at the end of Sec 4, with some notable exceptions... NCC cadets don't dig or do any strenuous stuff. NCC preps boys for NS and makes girls understand what boys go through.
NCC is not NS. You don't expect the NCC child soldiers to go to war and break the Geneva Convention, do you? Then again, if push comes to shove in World War Three, everybody will probably chip in to defend the Lion City -- probably the NCC too since they are well-trained. In WWII, before the fall of Singapore, many NCC cadets saw action by joining the real soldiers.
The "Singapore" chest tag just identifies the cadet/soldier as from Singapore, so there's no problem with NCC putting it on. The epaulette differentiates the NCC from the SAF.
NCC cadets are supposed to be as disciplined as the SAF.
In terms of capability, an NCC Gold unit has scored more than 90% in the BUC, which is just like the SAF. This means that it is proficient in shooting, navigation, fitness, IFC, arms drill, etc. Just like the SAF, but to BMT+ standard. You have to remember that the NCC is a combat-fit unit -- all take the NAPFA test every year. If no "kelong" was involved, I think the unit is well-trained -- probably better than most SAF non-combat logistics units in terms of combat skills.
The again, only a few units are of Gold standard. The Bronze and Silver units are not as good.
