"Attack craft are represented by 20mm square markers. When used in a wave, they must be spread and moved so they are always in contact with each other, and they cannot be stacked.
Attack craft waves must be assembled into the smallest circumference possible, such as a block of four, two rows of three, etc. For example, a single wave of eight ordnance markers cannot be stretched out into a single-file line eight markers long. On the other hand, individual markers not in a wave can be organized in any formation desired as long as no single marker moves farther from its launching vessel than its maximum possible movement."
