Australian/New Zealand Use of M16 Rifle in Vietnam?

[CINDERS]

Gate Guards, the one at the museum on Moore road in Dardanup is all welded shut no public access shame really I'd love to crawl inside one but at 193 cm probably a bit tall anyway public liability and all that guff.

If you expand this pic you can see the white impact area and the cracks in the left vision block. (Hold ctrl button and use mouse wheel scroll forward, use it to get the size back to normal scroll backwards.)
