"The major obstacle is that the contributing countries that send troops to NATO's forward battalions do not have sufficient capabilities themselves," the minister told reporters on Sunday.
"That's why we need to build them up and we are willing to contribute to that as well. As if we have a brigade, we can also contribute our share of capabilities to that brigade, which is what the Estonians, for example, are doing", the minister said.
Lithuania and NATO's other eastern members are pushing for a decision at the Alliance's upcoming Madrid summit in June to increase the size of the NATO multinational battalions deployed in the Baltic states and Poland to brigade-sized units.
The battalions were deployed here in 2017 to deter Russia, and increasing troops in this region is on the table amid regional security concerns following Russia's invasion of Ukraine.
"I believe that we are still leaning towards brigades, towards prepositioning ammunition, for example, and the deployment of weapons in the Baltic states as the experience shows that once a war starts, even if it doesn't start but Russia heats up the situation, the supply, as a rule, is severely disrupted," Anusauskas said.
