Some casualties were accidentally caused by air strikes, but many also are said to involve British troops firing on unarmed drivers or motorcyclists who come "too close" to convoys or patrols.
These troops have rarely been at the center of the action: in Afghanistan, they stay in the relatively calm north; in Lebanon, they patrol at sea, not on land.
Russia has already planted a flag on the sea bed at the North pole while Canada has increased funding for cold weather training centres and new patrol vessels
