APL Agate was back today on the G-6 Alliance service. (The ship made its first call July 10 - see: http://shipfax.blogspot.ca/2013/07/blog-post.html ) This time it had some noticeably distinct cargo - military vehicles perched atop the containers on deck. Most containerized cargo remains a mystery to the onlooker, but this time the army trucks were at least partially visible. Some were tarped, a pair were uncovered, and the tarp on at least one had already blown clear before the ship left Bedford Basin.
As a US flag vessel, it is presumably more than eligible to carry US military cargo, but it was not possible to identify the nationality of these trucks.
