It depends on whether the Russians can use their air superiority. The joker in this war is the effectiveness of air defense, both Ukrainian and Russian. That’s why Russian Air was unable to effectively intervene in the Ukrainian Kherson or Kharkiv offensives.
200 men is a couple of companies. Such a probing attack is a pretty good way to make the “withering artillery” reveal themselves for counterbattery fire.
That's why this is a WWI style trench warfare right now.
