let me just say this is really noobish (no offense really, just a fact)
- mech inf start with march. So they need only 1 medic in the stack.
- if you wait for mech inf to start domination or conquest, you'll end up at best with a time victory (except if you are a really fast techer, but usually this comes with enemies teching just as fast= nothing won, since you'll be facing mech infas too)
- Red cross is great, which as nothing to do with pentagon.
- for the price of the pentagon, I can have a whole army and not bother in the least about their promotions.
I'm not seeing the Newb-osity here.
Mech Infantry only need one medic in a stack. But if you have one city dedicated to producing Mech Infantry and that city happens to have Red Cross, then you're going to have a very comfortable level of Medic redundancy. The fact that these Medic units (Infantry or Mech Infantry depending on the era) have 2 promotions is just gravy.
I won't always build the Pentagon, but there is often a time of peace in my games when I'm thinking that I have spare capacity (and possibly a Great Engineer) in one city and that a nice juicy military tech is on the horizon. If I build the Pentagon now, I'll be pumping out that unit in each of my production cities with 2 promotions instead of 1. That's Combat1 and Pinch or City Garrison II or Combat1 and Medic out of the gate since Red Cross is something I have access to long after the Pentagon has been built by some civ. Or City Raider II tanks instead of City Raider I tanks.
That extra promotion is often the difference between my losing a combat and my winning a combat and finding more promotions available later.
Sure, I can switch civics. I can sit through endless turns of Anarchy to spend a few turns in (blech) Theocracy or (even worse) Vassalage. I could also go to war with a metric ton of units that each have 1 promotion. I could also just pony up the hammers and build the Pentagon. If my empire is big enough, the investment is more than justified. If my empire is not big enough to justify the investment, then I've probably already lost the game.
I tend to play Epic on Large maps with Low sea levels. I certainly wouldn't build the Pentagon on a Tiny Duel map just like I wouldn't build the Eiffel Tower or the Statue of Liberty in a One City Challenge. On the right map, however, the Pentagon is an outstanding wonder and when the Mech Infantry come out to play, you'll have a grand old time. That doesn't mean that you have to wait for Mech Infantry to do your invading. It just means that you get more benefit from your troops when they do come rolling out.
