well, i'll assume for the moment that i'll get whatever resources i need to build my choice. i'll further assume that i'll be limited to what i can obtain on rifts earth (no supplanting the naruni or splugorth here)
i'll further assume that i can't choose the Scandinavians i've been writing.
it would be a technology based army first and foremost. i'd have magic and psionic support, but those two are too random to rely on for the main force. Psionic troops would be screened to define their abilities, and the troops assigned according to their abilities. the PSI-detachments would be a type of special forces which are attached to regular units. Negapsychics and Psi-nullifiers would be attached to frontline squads and platoons, as well as the MP's, to deal with enemy magic and Psi. Bursters and other offensive Psi would be employed similar to weapons specialists. and so on. minor and Major Psi among the regular troops would be a factor for unit assignments similar to skills and experience.
Magic users would be expected to learn a core program of spells, to ensure some uniformity of ability. any magic user which can't learn specific spells, or cannot learn common spells (the basic spell list such as seen in RUE) falls under similar issues as psychics above. 'evil' magic like necromancy, blood magic, biowizardry, etc are all banned. likewise magic users are expected to abstain from sacrifices of intellegent beings, torture, and other such evil aspects. sacrifice for PPE is OK only under orders, and with unintelligent animals. (magic users can request live animals from the quartermasters corps, which supplies them out of the same sources used for fresh meat. members of the QC have to be on hand to ensure the sacrifice is a clean kill.. they also take the resulting carcass for butchering. waste not.)
part of the training for the army's magic users is the Talisman spell and the creation of PPE batteries. magic users which do not meet the physical capabilities requirement of the combat arms can serve in the QC creating PPE batteries and Talismaned spells for use in the frontlines. support spells (healing spells, toxin removal spells, camouflage spells, invisibility, and other such non-damage spells are a large part.)
Infantry would use versions of the Urban Warrior body armor, the L-20 pulse rifle (with tactical rail attachments to allow multi-optic scopes, under barrel GL's/shotgun/etc), the NG 6shot mini-missile launcher, the WI 40mm full auto grenade launcher, and the C-40 MG style railgun. heavy weapons troops would use a support harness to allow them to use heavy weapons without having to deploy in a stationary position first. (
Aliens style heavy weapons basically)
Infantry would be mechanized in an APC based on the IronHammer MBT (similar to the Israeli's Namer APC), a full squad of 12 in each.
the Main Armor unit would be a clone of the IronHammer MBT. Artillery and anti-aircraft would be based on the IronBolt MLRS, though 155mm howitzers on a IronBolt derived chassis would share the Artillery duty.
Powered armor support would be a mix of Shadowboy type suits in a 'mobile infantry' role, deployed from air mobile VTOL transports, and a transforming Motorbike/Powered Exoskeleton similar to the VR-038 from Robotech, which provides a light assualt role. (the latter would be able to use standard infantry gear, including heavy weapons)
i'd not use Piloted robots.. i love mecha, but i prefer decent MBT's for anti-armor work. though if i could build a decent Veritech fighter, i'd use that.
i'm not sure what i'd do for Airpower. i'm not a big fan of most of the canon Rifts fighters and helicopters, and using GAW stuff seems wrong.
