These are photographs from the year I spent in Borneo during my tour with 15 Intelligence Platoon,  5 Infantry Brigade (Airportable). The quality is not the best but it gives an idea of the country back before it became built up and they actually got roads.
The 22 Gurkha positions were about an hour by helicopter or 10 days by river and cross country, if I remember correctly.

5 Inf Bde was the last unit to serve at the Midwest Brigade Headquarters in Sibu.

There is something wrong with the link from this slideshow.  I will fix it as soon as possible (Jan 16)
