@Nicol.Bolas That's basically my experience - I never put GG units in harm's way. They only fight at 95% or higher, so a 3-promo unit could have reasonably won the fight at 80% odds or so.
But all this misses the larger point: Wars are about siege. If you're doing it right, siege damages everything to 25%-50% health, then the regular units just clean up in fairly easy fights. The only time you need a strong attacker is if your siege didn't do it's job (meaning the enemy unit still has close to full HP).
(For more on why siege is necessary, see the stack o doom guide: http://forums.civfanatics.com/showthread.php?t=185838 )
Siege units are there to die, so you can't put a GG on them. The only way to help siege is to settle the GG. And once you have good siege, ordinary 3-promo units can mop up easily.
(This is the same reason Charismatic is better than Aggressive - wars are about siege, not melee. See http://forums.civfanatics.com/showpost.php?p=8824380&postcount=106 ).
Welcome to the forums!
The point about siege is definitely good - most newer players don't use enough. I rate Charismatic well above Aggressive, but not due to war. Charismatic is better for most wars, but Aggressive is better for the rush. But Charismatic gives the happiness boost as well which is really nice.Like you, I don't put my GG units in harms way. Of course, my only GG units are supermedics, everything else gets settled.
Note: I think the Military Academy question is partially decided by what speed you play on. Normal it might not be worth it if you can get out units in 1 or 2 turns. On Epic or Marathon then the Military Academy becomes more attractive.
