If directive don’t change much, I’ll write stuff decades ago.
If there’s no operation done onto the limbs, it’s unlikely to go below Pes A, B or BP. Active NSF & Reg will have to go physio. But excuses MC off that injure area will be given. Pes C1 (upper limb), C2 (lower limb) & C9 (back) are for non-permanent disable injury. Pes E is for permanent disable injury.
To be exempted for IPPT, make sure that there’s 6 months of light duty MC without a single day break for that window.
For active NSF Reg in non-combat unit, just tell MO & he can issue light duty 61 days straight (except in BMT). If need to see gov hospital specialist, just tell MO to arrange or ownself arrange If need to see private specialist, svc men is to arrange himself.
For active NSF Reg in combat unit, light duty MC all depends on unit CSM, OC, RSM & CO.
For NSmen & before enlistment svc men, just get light duty MC from GP. If need to see gov or private specialist, svc men is to arrange himself.
When seeing specialist, please request the specialist to write a Meno calling the camp MO to apply for medical board review for a downgrade or upgrade for the svc men. Then wait for good news.
(Rumor) to buy private specialist letter, please check with ex & present men & women from Army Logistic Formation for contacts. Decades ago was S$100. Now, probably S$1000 or 10000. Or go third world country buy cheap specialist letter. If medical board requires evidences, lab technician can adjust the machine until it shows a problem.
Take note, that all specialist & GP from gov or private & including camp MO or specialist from medical board; all have worldwide recognize MBBS. Unlikely, Meno & MC will be turned down for life threatening situation.
During ICT, if don’t want to go outfield, just get light duty MC from camp MO & sleep in bunk. Take note, those on-the-ball combat NS unit may off-pro the svc men or write high-key clock as low-key for not going to field. Using low-key method, svc men need 20 low-key to MR ROD.
For Pes F, please read my old tread on army issues:
