The US Mk19 is also usd by the ADF, and proved very effective in the post S11 conflicts we have been fighting in.
WRT to pic in the above post, thats good fire power along with the 12.7!
I would not wanna be on the business end of 40mm HEDP, and the 12.7 AP, API, APIT. For ops the ADF does not even have ball in the link.
Wicked.
