The war in Ukraine is reshaping the strategic landscape of Europe. While Western and Eastern European nations within the NATO alliance recognize the Russian threat, each day, NATO nations bordering Belarus and Russia feel the immediacy of the threat.

In an exclusive interview with VOA’s Eastern Europe Bureau Chief Myroslava Gongadze, Lieutenant General Charles Costanza, commander of the U.S. Army’s V Corps (also known as the Fifth Corps) in Poland, discusses how NATO adapts to Russia’s evolving tactics while defending its members’ borders.

This interview has been edited for brevity and clarity.

VOA: Can you explain the different threat assessments from Eastern and Western European partners of NATO regarding Russia?

Charles Costanza, commanding general of the U.S. Army’s V Corps: Clearly, in the eastern flank of Europe, the threat is real. They’re on the border with Belarus and Russia, and so, they see that threat every day differently. You see recent open-source reporting on the Russian UAVs [unmanned aerial vehicles, or drones] coming over Romanian territory and Lithuanian territory. Those incursions have increased. You see the sabotage operations going on throughout eastern flank countries and Eastern European countries. So, Russia is increasing that, short of … challenges and interference [that would trigger the NATO mutual defense clause].

VOA: Do you think Russia is doing it deliberately?

Costanza: Of course, they are. They weaponize immigration — I say “weaponize” deliberately. This weaponized immigration is happening in Poland, it’s all been driven from Russia to interfere in Eastern Europe. Moldova is a near-term example with their elections. Russia is actively interfering in those elections to try and shape them in a pro-Russian way. So, all that is going on right now. So, that’s part of this threat assessment piece that isn’t necessarily impacting the Western European countries as much as Eastern Europe.

VOA: How threatening is Russia’s military?

Costanza: I think there’s a view that Russia is going to take three to 10 years to reconstitute, and I think that we need to look at that a little differently. Russian armed forces, ground forces right now, are actually bigger than they were before the war with Ukraine started 2½ years ago, despite the losses of open-source reporting [of] 600,000 casualties that they’ve incurred during the course of the war.

They may not be as well trained, but they’re bigger. Their industrial base is on a wartime footing. Their mobilization base is on a wartime footing. They know they’re fighting a Western-trained, West-equipped country with Ukraine. They’re learning how to defeat those capabilities and those systems over the last 2½ years. So, they’re modernizing their force based on the lessons that they’re learning, and I think that’s something we should be concerned about. They’re modernizing their equipment. They’re changing the way that they fight based on learning how to fight against Western-trained forces in Ukraine. And I think that should be a concern for all of us. It clearly is to our Eastern European allies.

VOA: How are you preparing to defend and deter?

Costanza: First of all, to maintain a high stance on readiness from a U.S. forces standpoint but also the NATO standpoint. At the Fifth Corps, one of the key things we do as partners with our multinational corps and multinational divisions across the eastern flank of Europe [is] just to help build their war-fighting capability as they field new capabilities. HIMARS [High Mobility Artillery Rocket System], for example. Apaches [helicopters] — with Poland just purchasing 96 Apaches from the United States. So, we help them to employ those things, those capabilities. But how you employ them at the corps level, and how you employ them at the division level, we can help, and we do.

VOA: General Valerii Zaluzhnyi, the former commander in chief of the Ukrainian Armed Forces and now ambassador to the United Kingdom, recently gave a speech at Chatham House in London in which he talked about the technological advancements of this war, and how this is a different war than NATO was prepared to fight. How would you assess NATO’s capabilities today?

Costanza: I think you’re exactly right. And those are some of the comments that were made by our NATO partners in this event. I think that the United States is kind of setting the standard on that with a new program that our chief of staff of the Army [General Randy George] has talked about, which is transformation in contact. So, for the U.S. forces that are rotating over here to Europe, we’re modernizing them with equipment that’s available right now. So, instead of going through our normal four-year acquisition process to get new equipment, we’re taking things that are available based on what we’re watching happen in Ukraine. … So maybe that can be a model for our partners and allies.

VOA: We talked about NATO capabilities. Now I want to go back to Russian capabilities. How advanced do you think they are right now?

Costanza: I think the biggest concern is what I said before: They know they’re fighting Western-trained and -equipped forces. And so, as they modernize based on the lessons that they’re learning — not just their equipment, but how they fight — they’re really sharpening their ability to fight us in the future. And I think that’s something we need to be concerned about.

So, those things I just talked about that we’re trying to rapidly introduce into our brigade to execute the transformation, contact — the UAS [Unmanned Aircraft Systems, or drones], the border, ammunition, the counter UAS, the EW [electronic warfare] capability. And how do you synchronize all of that capability so that you can really, rapidly strike and kill targets? They’ve learned how to do that. And so, we need to be able to do that and do it better than they do.

VOA: Russia is gaining support from China and North Korea right now. Are we ready to face this threat?

Costanza: The lessons that I was talking about, the reasons we should be concerned about Russia — they’re sharing those lessons with China, with Iran, and vice versa, the capabilities that Iran and China are providing. And now you see the North Koreans, as well. North Korea is now providing, I think it’s an initial batch [of] open-source reporting, of 4,000 North Korean soldiers. I think that could potentially just be a starting point for what they provide in terms of manpower to Russia. And I think that’s a problem near-term here in Eastern Europe, because as we talked about before we started, the challenge for Ukrainians is people. It’s the amount of people that they have to put into this fight. And Russia doesn’t care how many losses it takes. I mean, 600,000 [casualties], and they’re still throwing more manpower at it and don’t even blink. Ukrainians can’t afford to take those losses. I think that’s going to be the limiting factor for that as we move forward, watch this war continue into this third period.

VOA: There are different assessments of threats between, let’s say, the political part of the NATO alliance and the military part of the alliance. How are you finding that common ground?

Costanza: Yeah, I think it’s just constant dialogue, right? And so, I know we do that at different levels. So, the combatant commander, the U.S. combat commander, has those discussions at the national levels with our NATO partners and allies. We all live in Eastern Europe, including myself — in Poland. We all see that threat the same way. It can be near term.

VOA: What do you mean by the near term?

Costanza: I think, one year, two years, three years.

VOA: And you’re trying to be ready for that?

Costanza: U.S. forces are ready, and I can tell you, our NATO partners and allies are ready. And we’re just continuing to build capabilities.
