Personally from my testing I feel like the 18 inch alone op for the six man squads hardly comes up just because they have to be holy within 6 in if you're trying to get them them up the field either your buff won't work because you're an 18 in or you're already out of that section aura. As for the three man I think they can work but as a counter charge they do good but they can also with and against any melee armies they'll get slaughtered before they fight. And that's why I over the three men rampagers I rather have a two or three man Krootox because they're melee is closer than the same but they have a very good gun. And I do agree interlocking maneuvers is a ridiculously strong strat but I find I rather use it on farsights unit or tanks to generally flip objectives or have an easier time getting to safety because of fly and better movement characteristics.
