Finland’s military has begun preparing rapid response units for deployment along the Russian border, DefenseNews reported. The move follows an increased push for militarization which has been ongoing since Finland’s elections in April. The elections were followed by a series of mysterious incidents in which Finland’s military claimed that it spotted “underwater objects” in its territorial waters, which could not be found on further inquiry.

The legislative basis for the new units is still lacking, according to the chairman of Finland’s Parliamentary Defense Committee Ilkka Kanerva. “New legislation is needed to enable the armed forces to recruit reservists in a transparent and efficient way. Under the present system, reservist contracts do not stipulate exact service times or how quickly reservists can be mobilized and armed,” Kanerva said, as cited by the publication. MORE
