How many Westerners are fighting in Ukraine?

There may be more foreign boots on the ground — troops and mercenaries — than you think

A March 14 update on the number of foreign mercenaries provided by the Russian Defense Ministry, which has an interest in muddying the waters on these figures, claims that 1,005 Canadian mercenaries have gone to Ukraine to fight. It claims that at least 491 of them — nearly half — have been killed.

And Canada is not number one on that list.
According to the Russian update,

1. 2,960 mercenaries have come from Poland with 1,497 of them reportedly killed.
2. Number two is the U.S. with at least 491 of its 1,113 mercenaries killed.

The update says that mercenary fighters have come from NATO members Romania and the U.K., while France has been the source of fewer: 147 French nationals have died out of 356 who have gone, according to Russia

Your information is better than Galt's blowing smoke, but it's subject to propaganda censoring. There won't be any official announcements from either government.
