在這次烏俄戰爭中，發現有不少外國傭兵參與，主要的原因包括：

大多數外國傭兵通常是出於經濟考量而參與軍事行動。他們來自經濟較不發達的國家，而傭兵工作提供相對高的薪資和福利。例如，尼泊爾是傭兵的主要輸出國之一。

一些外國傭兵是高度訓練和經驗豐富的軍人，退役後加入軍事行動，可能來自國家的軍事部隊或私人軍事公司，如俄羅斯的瓦格納（Wagner）公司。

外國人參戰有時會受到政治和地區性因素的影響參與衝突。例如，政治動盪、內亂或地區性戰爭可能導致對額外軍事力量的需求，外國傭兵則被視為填補軍事需求的方式。一些國家的政府可能會出於政治立場提供支持，甚至默許其公民參與外國傭兵活動，包括提供培訓、裝備或資金。有些人被冒險和挑戰吸引，希望參與戰爭或衝突以經歷極端情況，或追求個人冒險精神。

2022年11月5日，來自花蓮吉安鄉的25歲曾聖光加入烏克蘭軍隊，在烏克蘭東部盧甘斯克（Luhansk）的戰場上因失血過多而喪生。目前已知至少有4名中國大陸人加入俄羅斯軍隊，其中首位陣亡的是一位山西籍士兵，隨後是2023年12月戰死的重慶籍戰士趙睿。仍在戰場的有一位來自東北的戰士，他的抖音帳號《在俄猛虎》和來自廣東的小強。然而，他們紛紛表示在裝備和訓練不足的情況下，被派往第一線戰場，隨時都可能喪命。儘管希望盡快回到中國，由於已簽約，俄羅斯不可能讓他們提早返回中國。

In the current Ukraine-Russia war, it has been observed that many foreign mercenaries are involved, and the main reasons include:

Most foreign mercenaries typically join military operations for economic reasons. They often come from less economically developed countries, and mercenary work offers relatively high salaries and benefits. For example, Nepal is one of the major source countries for mercenaries.

Some foreign mercenaries are highly trained and experienced military personnel who join military operations after retiring. They may come from their country's military forces or private military companies, such as Russia's Wagner Group.

The involvement of foreigners in conflicts is sometimes influenced by political and regional factors. Political instability, internal conflicts, or regional wars may create a demand for additional military forces, and foreign mercenaries are viewed as a way to fill this military need.

Certain governments may provide support, either due to their political stance or by tacitly allowing their citizens to participate in foreign mercenary activities. This support may include providing training, equipment, or funding.

Some individuals are attracted to the adventure and challenge, seeking to experience extreme situations or pursuing a personal sense of adventure.

On November 5, 2022, 25-year-old Zeng Shengguang from Ji'an Township, Hualien, joined the Ukrainian military and tragically died on the battlefield in Luhansk, Eastern Ukraine, due to excessive bleeding. It is known that at least four mainland Chinese have joined the Russian military, with the first casualty being a soldier from Shanxi, followed by the death of Zhao Rui from Chongqing in December 2023. There is still a soldier from Northeast China on the battlefield, identified by his TikTok account "在俄猛虎" and a person from Guangdong known as Xiaoqiang. However, they have expressed concerns about inadequate equipment and training, being deployed to the front lines, and the constant risk of losing their lives. Despite their desire to return to China as soon as possible, due to contractual obligations, Russia is not likely to release them early.
