{{TTS/1| Bus Service 177}} is an inter-town bus service that connects the residential estates of [[Bukit Batok]], [[Bukit Batok|Hillview subzone (Bukit Batok)]], and [[Bukit Panjang]] to Ministry of Defense Headquarters (MINDEF HQ @ Gombak Drive). This service operates on a non-stop express sector between Hillview and Bukit Panjang via Upper Bukit Timah Road due to the temporary closure of Hillview Link to facilitate the construction of NS Hub.

This service is the only service that allows commuters to enter a military compound without authorisation, which is typically restricted to non-military personnel. However, commuters are not permitted to take photographs or record videos onboard as the service operates within the military camp compound.

On the eves of Christmas, New Year, and Chinese New Year, evening peak-hour departures will be brought forward to the afternoon. Revised timing will be announced by the operator closer to the respective dates.
