Seriously, the AI needs to value these. It's so easy to crank up your research for a few turns, bum rush the soldier techs, and have 3,000 soldiers take out 12,000 with just using traditional warfare. It gimps a very useful strategy of just soaking up with numbers if you research ZERO soldiering techs.
Take for example.. Playing on Tough with the Terrans and it's late late late late in the game. I've conquered all other races and I am mopping up the Arceans. I have 120 soldiering bonus vs. their 40. This is the higest number I've seen, but to be that late in the game? Value this IMPORTANT tech. more.
