@mikey_ez: Let me state this, first off its movie version for the orcs, second aressword did say movie versions for team 1 and then real life versions for them. Honestly Wut broke this down, and honestly I'd say he knows a lot more than what you're putting into this. The op said in the rules
- weapons have been upgraded to steel; this does not mean that they will weight any less or more, also this does not change the look or the way their weapons will and would work.
This means that argument about bronze vs medieval is literally shot down. Orcs had decent gear but was crap compared to dwarven or elf, it was about the same as steel.
Honestly Wut's argument
Movie Version: Spartans still won't know how to fight within a siege very well, and Leo seems far too headstrong to be open to suggestions from the Samurai and Romans, so you will probably have some on the walls as well as some in the streets in their 'formation'. Sadly, they don't hold this formation... ever... and prefer to break it and go fight in slow motion because HELL YEA!... Anyways, their curved blades aren't going to be as effective against the orcs as it was against the 'Persians' due to the orcs making heavier usage of heavier armor. That said, a 300 spartan is going to be a way better fighter then the movie orcs and larger and stronger. Their lack of armor still hurts them a lot. (This is not even counting that said orc shortbows were able to pierce Gondorian plate.... somehow...)
The movie samurai are also hindered because while some use yari and yumi, the vast majority used their swords which... doesn't do them any favors here. Katana's aren't meant for continued, prolonged use in a battle (also why they carried more then one), and during a siege with lots of close combat fighting against Orcs with chainmail, the Katana is not going to preform as well as many people think they would. The Samurai do have armor that is good against arrows and slicing weapons, so they should do fine, but they won't be as effective.
The Romans are the all-stars here as I mentioned before. They have good armor, formations, and weaponry for holding streets and even wall-fighting. They bring a good amount of archers and siege engineers for the trebuchets on the wall. If they do not make Maximus the overall commander then they are probably in trouble because he has the best troops in terms of being suited to a siege, and being a Roman General is, no doubt, at least familiar with siege warfare on a city like Minas Tirith (Tall, stone walls and tight streets).
Britions and Highlanders are meh. They are good light infantry and would do better on the walls or acting support for the other three. They are more akin to being warm bodies to fill the ranks and hold the walls then anything else.
Since they only need to hold for three days in a city with ... 6 or 7 walls, I can't remember, with tight streets then they should be able to do it.
Real Life Versions of Spartans and Samurai: Spartans wouldn't quite know how to fight within a siege very well. They never had a wall because they were very proud of their warriors and had a 'come at me bro if you think you are hard enough' attitude. However, they are armored and utilize their phalanx formation to a credible degree which is going to be very, very, very, very effective in the tight streets of Minas Tirith as well as very effective against Trolls. (Spears > Swords against a large creature). They have short stabbing sword which is far more effective then the mutated scimitar they use in 300 when going against... almost any form of armor, and the orcs did like to use chainmail with metal plates here and there. (Leo is not nearly as 'great' as the movie version made him out to be.)
Real Life Samurai would be better as they will prefer to use bows and spears compared to the katana loving ones we see in the Last Samurai. Katanas were akin to our pistols we give to our soldiers, it is a sidearm and not meant to be the primary weapon because it isn't as effective. The fact that the Samurai will be using Yumi is a massive boost as the one thing team 1 is lacking is in the archer department. The Scottish Highlanders in Braveheart was light infantry, I cannot recall them using bows. The britons (been awhile since I have seen that movie) also didn't make good use of the bow and were also light infantry. The only ones who really bring archers here are the Romans (using hte movie version), so having more archers would be a massive boost.
Real life will preform better because they are better armored (in the case of the spartans) and use their formations to a much better degree.
Most of the archers are going to be from the Samurai(Maybe 3kish) and maybe 2 - 2.5k Roman archers. I will toss in 1k briton archers just to be safe. So, being optimistic, that is 6k archers with 44k infantry... not what I would call optimum when guarding a city, but better then nothing.
I would place the Britons, Highlanders, and sprinkle Samurai among them on the walls (The Samurais being great 'all rounders'). The britons and Highlanders are lightly armored and more 'brawlers' then soldiers. Fighting on a wall would encourage them as well as help with their lesser armor and suit their fighting preferences. The Samurai would be there for added skill and heavy infantry to help hold.
The Romans and Spartans would have the streets. Roman Pilums would be very deadly when thrown into a narrow street as they are, pretty much, guaranteed to hit something. Both Romans and Spartans have amazing formations for fighting in tight, narrow areas when flanking and rear attacks are not a thing. I would also sprinkle Samurai units in the streets as well as they were very adept as using their Yari spears in tight formations.
The only way they are failing is if the Trolls can break through, but given their numbers, I highly doubt they will be able to push through every wall and street when they are packed with the tight formations of Romans and Spartans in three days. Team 1 should win.
Literally says why team 1 should win, everything he says isnt law, but I find it hard to disagree with him and mordor didn't barely do jack to the defenders even with all the numbers they had and all the siege. In other words team one would stomp mordor if they didnt have trolls. Period.
