Should the Army secure the borders?

[Kagemusha]

Does anyone else know what other countries use to secure their boarders? I genuinely don’t know but from the 007 movies it seems it’s always the military.

I can only speak apart from my Country but our Border Guards are military trained.While mostly they work almost as police force,but incase of War.They are the first ones to start slowing the enemy.Many of them have military training of Tiedustelija= Ranger.
