• The announcement must be from a Baltic government or military source explicitly stating they are sending ≥ 300 military personnel to Ukraine.

• The announcement will be sufficient to resolve the question Yes.

• The personnel must be in Ukraine for the purpose of participating in direct or indirect combat roles (e.g., personnel sent to train and / or advise Ukrainian troops do not count.)

• The 300 personnel need not come from a single Baltic state.

Examples of indirect military roles:

• relieving Ukrainian troops on the Russo-Ukraine border;

• manning artillery and air defence weaponry; and

• performing supply missions and medical evacuations.
