The UK MOD, Defence News website covers the visit to Afghanistan by Brigadier General Tua'aika Uta'atu, Commander of the Tongan Defence Force including the news that Tonga is to commit 200 troops to join the ISAF force in Central Helman Province. You can read it here
200 troops is a HUGE commitment by Tonga. So too is sending them to Helman Province where the bulk of the fighting is.
And nary a squeak in the New Zealand media about this.
