We've got a further update for you now on the state of the fighting in Ukraine - this time from the UK's Ministry of Defence.
It says Russia appears to be following "traditional military plans for entrenchment, largely unchanged since the Second World War".
The MoD highlights Moscow's "considerable effort" recently on constructing front-line defensive positions.
It suggests such tactics have been "largely abandoned by most modern Western militaries", and are vulnerable to precision strikes.
