 So my name is Therong Nelfusta and I work with the Norwegian Defence Staff in J79 and I'm the Norwegian Head of Verification. I have been the head of the Norwegian Verification since 2016 and I've also been the head of the observation for Trident Juncture in 2018 and Recall Response in 2020. With this observation 17 nations said yes, so we have 17 nations present and 33 observers. We've been visiting all brigades that's been here in all subunits and they're the brigades I don't know if you know about, they're from Norway, they're from Sweden and Finland, they've been French, they're from the US. There are 27 nations participating in Recall Response so there's a lot of people and about 15,000 of them are on land and the rest which I think is about 15,000 is taking part in the, out in the ocean and out in the air. But the Vienna document we're mostly concerned about land forces so that's where we are focusing. Our aim is to show that this is a non-stretching exercise for our neighbouring nations or any nation at all. Recall Response is a very big exercise, over 13,000. Norway had to invite all the members, member countries, 57 member countries of the organisation for security cooperation in Europe. So we are now visiting a subunit that we just met here which is a French subunit with some marines also embedded and we are here from a perspective of showing that this exercise is a non-stretching exercise, it's transparent and open and according to the information that Norway has sent out, previous to the exercise. And that is such a large exercise. We sent out information to all the nations of the OCC two years in advance just to make sure that they knew about this exercise. We are here as part of the Vienna document which is an arts control treaty and it's very specific and detailed about what kind of information these military brigades are going to tell us observers. So in order to show how transparent we are. And so all the brigades is following it to details very well and even more. So we call it not only in the letter of the Vienna document but also in spirit which meaning giving more information shows that we are very transparent and open about our military activity and this is called unusual military activity because it's larger than just a small training event. So that's very important. The group here of observers have been asking a lot of questions and the troops and the commanders and the soldiers we met has been very open and friendly and showing us how their goal is and the exercise and how they've been treated here and how the difficulties and challenges they have being the soldiers in Norway because this is what Norway this exercise is for us to defend our countries and to be able to invite allies into Norway and have a lot of these countries from France it doesn't have this cold weather or Spain and stuff like that. So from the Norwegian perspective it's very good to have allies come and train and exercise with us and from an arch-control perspective it's been very good because the ally who's also signed the Vienna document has been very open to the observers. My name is Ragnil Husta and I'm with the Vienna document of observers here in Exercise Call Response.
