For me the worst military UU ( it is hard to argue against the lack of fighting abilities of the Indian UU
) is the Korean UU. A military UU that can't kill in offense... hooray ( P.S In MP it might be a quite useful unit, with the human love for melee units and battles in the open ... but in SP, with AI love for defending in their cities with archery and/or gunpowder units ....
) C'mon, even B. Phants can kill in offense
About musketeers ... well, I guess that a lot of people uses them as regular 1 move units
, as part of a stack with maces, siege and pikes. obviously they look weak if you use tham that way, in the same way that combining gunships with infantry is a bad idea
Musketeers shine when they move with knights ( at best ) against cities with little or no defense ( spy revolts to the win ) ... if you don't do that, they aren't better than regular muskets
@Rooftrellen
I have to disagree with you in atleast 2 UU, the Spanish and the Celt one. It is not hard to get the techs to get cuiraseers ( and the spanish UU ) via the Liberalism path ( tech lib, get natio, trade for/research music + gunpowder ( this one is better to research ), tech Mil Trad ) and the spanish UU , besides having terrain defensive bonuses and fortify ( making them considerably harder to dislodge than a cuiraseer ) have a bonus vs their better counter ( pikes ) . Mass Conquistadores combined with spy revolts makes a good window of attacks IMHO.
About the Celt one: c'mon, you really think that the Guerilla line is about defense? Guerrilla line is ALL about offense ... just look at guerrilla III : + 25% attack vs hills + 50% withdrawn chances ... or even guerrilla II , with the double move on hills ( you can chop forests, but you can't raze hills
). That makes the G Warrior the only melee unit that can withdrawn and given the AI love for hill cities .... The G. warrior also can be built with copper ( instead of only iron ) and comes with a free promo that it could never get by normal means ( and opens a promo line that would be normally closed ) ... a CR I Gerrilla III G. Warrior ( 8 XP, given that both Celt leaders are Charismatic ... ), a very easy to get unit, will have 50% withdrawn chances, double movement on hills, +50% defense on hills , 30% vs cities in flatlands and 25% vs units in hill tiles ( making a nice 55% vs units in hill cities ) ... I can definitely assure you that this is a combination hard to beat for the price it comes and it is even better with the Agg free Combat I in top ( read Boudica )
