@Arcologist, @Cyc: Thank you for your insightful responses. I am currently creating tables of officers and equipment for two different combined-arms companies, each of which will have four 'Mechs, eight vehicles, and two AeroSpace Fighters. The 'Mechs will be different for each company, but will total 240 tons. The vehicles will probably be the same for both companies, but I am leaning toward an Armor Lance and an Artillery Lance for each company. Then the Air Lance will be composed of two Stingray AeroSpace Fighters, which again average 60 tons, just like the 'Mechs.
It might work to just call the 'Mechs "Command Lance", followed by "Armor Lance", "Artillery Lance", and "Air Lance" for those units.
