It's at Kelantan Lane. Near Sim Lim Tower.
Once a sect comd in my coy came to me with 'problems in urinating'.
Without going into too many details (there are women here, after
all) I realised that he had gonorrhoea. My suspicions increased
after he told me that he had a fling with a 30-year old married
woman two weeks before. 
The thing is, we were all in the jungle then, in the middle of the
night doing a coy-level exercise. But since there was no time to
waste, I commandeered the coy's 5-tonner and sent him straight to
the medical center.
At the medical center, the MO gave him an instant ATTC and ordered
him to go to the clinic at Kelantan Lane the very next
morning.
My Encik was initially furious with me for stealing the coy's
combat train, but after I explained the situation, he turned his
fury to that said sect comd. 
Anyway, the sect comd was lucky... while gonorrhoea is terrible, it
is perfectly curable with antibiotics. Needless to say, the
experience scared him off his promiscuous lifestyle. 
Heck, it convinced me once and for all the virtues of chastity.
