My tactics are radically different by ERA . Star League had the most use of WMDs during the Reunification War.
Succession wars I used standard lance of Centurion and Trebuchet as well as some heavy hitting Tanks or Mechs. Heavy installation and use of Hitches, Trailers, and recon cameras .
Clan Invasion ERA : C3 ; TAG ; Homming Arrow to make holes and Semi - Guided LRMs to Exploit them.
Jihaad much the same as Clan ERA but Expect an ECM rich situation .
3058-3078 dropped Artemis IV FCS as too many stock mechs have ECM installed even to its detriment.
Republic ERA heavy Wight use in Urban combat .
Nearly all experimental tech becomes Advanced. ECM becomes gradually less prevalent Artemis IV more viable
Dark Age this ERA was reflected by having all this shiny new tech getting their ass kicked by tried and true tactical doctrines. ECM becomes one or two per company at best .
Il Khan nearly all experimental and Advanced becomes tournament legal . Mature I know hiw ro use the new tech tactical doctrines have happened so getting wrecked by 80 + year old equipment happens less.
