Robert Le Blanc (subject of and co-author of the book “Silent Drums”, has shared (on Facebook) about an hour of rediscovered Viet Cong footage from 1967, silent, black and white.
This reminds me of the Wikileaks “Collateral Murder” from Iraq (April 7, 2010). But this is actual enemy footage, the kind of stuff that might have been shown in Basic Training at Fort Jackson in 1968 if the Army had had it then,
As embedded, the footage will not play when using "https" (just use http). Or you can use this direct link,
