London (CNN) The Pentagon released a map this week showing coalition forces have taken back 25-30% of Iraqi territory seized by ISIS.

The map, above, shows gains in key central and northern areas of Iraq where the terror group was previously the dominant force.

The gains made in the fight against the terror group by Iraqi security forces and coalition air power certainly look impressive -- although as the U.S. Department of Defense acknowledges it's a dynamic conflict and territory can change hands depending on "daily fluctuations in the battle lines."

So, how exactly should we read this information? What does it say about the wider fight against ISIS?

CNN asked Afzal Ashraf, a counterinsurgency specialist and consulting fellow at the Royal United Services Institute to give us a steer on what this new data tells us about the fight against ISIS in Iraq.

Below is an edited version of the conversation.

CNN: So, is the tide turning in Iraq -- is the coalition winning?

Afzal Ashraf: When it comes to insurgencies it's always problematic to think about the tide turning in terms of territorial gains because insurgencies by their very nature are extremely good at adapting to change.

The one difference between ISIS and insurgencies in general is that ISIS declared itself a state, a caliphate once it had territory so any loss is very strategic loss of prestige and image for them.

(There have been) significant gains against ISIS -- particularly in Tikrit -- and it's no coincidence we've seen ISIS make spectacular attacks in refugee centers in Syria. It's asymmetric warfare, they know they cannot hold conventional force back for very long so what they do is they withdraw ... then take initiative elsewhere.

They have to distract attention from those losses by gains and attacks elsewhere. It continues their image of initiative, of shocking, of reshaping the world -- which is what they are trying to do.

CNN: What does the map tell us about the coalition's strategy?

AA: It's very telling. There are losses but most of the losses are around the edges of their territory and what that means is a very conventional push forward by the Iraqi forces. It's a push against the front line of ISIS rather than being brave and creative and going in behind ISIS's lines and breaking it up.

What this isn't is using maneuverist warfare -- which is a military philosophy that exploits the capabilities of conventional forces to project power by using air forces to take land along main supply routes and put friendly forces on that land to cut land into chunks which causes massive disruption to command and control and their supply chains which can cause forces to collapse much more rapidly than a frontal push.

The capability you need (for this kind of warfare) is much more high-tech than the capabilities the Iraqis have. Those capabilities are available in the region -- Jordanians, Egyptians and other forces have helicopters and aircraft -- and it's very interesting that the Middle Eastern nations have not developed an effective coalition to target ISIS which is an existential threat.

CNN: What about Ramadi? ISIS seems to be winning there.

AA: Ramadi has been a potential battlefield for the past decade. But in this context (ISIS) will ... be pushing in Ramadi because that's an area they have lots of support. It also diverts their attention away from losses to their gains. The concept of success is hugely important to them -- it's what sustains the recruitment effort of ISIS. Nobody wants to join a bunch of losers, so it's very important for them to be seen to be succeeding.

Above all this is a rhetorical war that is being fought deliberately in the media. They are losing so of course they are going to try to distract us by destroying ancient statues in Nimrud and killing refugees in camps like Yarmouk. But where it counts they are not standing and fighting.
