Rhodesian Forces Website An excellent starting point, with links to all units/ history/ individuals 

Or try Richard Allport`s http://www.rhodesia.nl - which has a huge amount of material to download, as well as a number of book reviews

ARMY
British South Africa Police "official" website

Rhodesian African Rifles Unfortunately, this site recently disappeared. The other 'official' Rhodesian sites are now your best bet. With the standard provisos! 

Rhodesian Light Infantry - with videos to download

SAPPERS (military engineers) 

AIR FORCE
(Amusingly, a search-engine entry of "Rhodesian Air force" came up first with links to the UK RAF careers site, then a variety of sites offering low-cost flights to Harare. This clearly means something ...) 

No specific site seems to exist, so the air force section of the Rhodesian Forces pages offers a good starter 

SPECIAL FORCES
SAS C Squadron's excellent (if slow) "official" website. 

Selous Scouts

South African `Parabats

CIVILIANS
Rhodesians Worldwide - an (inevitable) choice - almost certainly the best overall starting point
GENERAL RHODESIAN HISTORY
The Wikepedia links page on Rhodesia is a great starter.
