That would be one of the ways that you could describe how the assist function is defined.
You've seen it reported on, I've spoken of it, and it is absolutely a part of the fact that we are there with them and have the responsibility to protect ourselves, and as we have explained repeatedly, the responsibility for the defence of others if they are to be overwhelmed.
A great example is that we have weaponry that allows us to not be on the front line, to be well back from the front line, well back. If a heavily armoured suicide vehicle laden with explosives is approaching the line or exposed peshmerga forces and its detonation would result in the death of dozens of them, or civilians, then we have the ability with the weapons we have to eliminate that threat before it materializes.
