5 ninjas would win against 5 vikings

How will they be fighting?First, since my opponent has not specified how they will be fighting, I will say that they are fighting on an open battlefield at noon near the ocean.I will now add to my opponent's list.Viking facts1. Strength advantage2. Heavy weaponry but slower than ninja due to massive weight of weapons and armor3. Spear4. Axe5. Sword6. Dagger7. Shields8. Ships (Best sailors of the time)9. Shield Wall strategy10. Javlins11. ArrowsNinja factsMy opponent has forgot to add the numbers 1 and 13, so I will fix it.1. Ninjutsu (Kind of like Kung Fu)2. Kyusho points(pressure points)3. Assassins4. Can use darkness as an advantage5. Can deprive others of vision smell and hearing6. Ninjato (A type of sword.)7. Kusarigama (A mace-like weapon)8. Fukyia (Dart-Blower)9. Poison10. Stalkers who can live on there on in nature.11. Can take out many enemies at one time12. Acrobatics equivalent to parkour13. Can throw shuriken (Length varying with different ninjas)Now I will eliminate some of my opponents points.Kyusho points- Will not work on viking armor.Assassins- Open battlefield, assasins would be very ineffective.Can use darkness as an advantage- We are at noon, no darkness.Can take out many enemies at one time - So can vikings.Can throw shuriken- Would be ineffective on viking armor.Fukyia - Ineffective on armor.After eliminating some of my opponents points, the list is down to this.Ninja1. Ninjutsu (Kind of like Kung Fu)2. Can deprive others of vision smell and hearing3. Ninjato (A type of sword.)4. Kusarigama (A mace-like weapon)5. Stalkers who can live on there on in nature.6. Can take out many enemies at one time7. Acrobatics equivalent to parkour8. PoisonAs you see, Vikings have more advantages than ninjas.Rebuttals "They can hide in the darkness and have up to 40% more visual capabilities than a normal human."Blogspot is not a valid source. Besides, I cannot find anywhere on Google that a ninja has 40% more visual capabilities. Probably more modern myths."Ninjas can poison a viking from very long distances using a blow dart."It's called armor."The ninja also have the kusarigama and the ninjato, and wakisahi. The kusarigama alone gives the ninja an amazing advantage. It has a iorn or steel ball attached to an iorn chain of about a couple feet and a kama at the end. This weapon allows for great transistions from far to close range. The ninja can knock them on the head causing brain injury and then move in close and finish the kill to the heart with the kama..................or just force others to keep there distance."1. Armor2. Vikings have similar weapons."Strategically ninjas would succeed"Actually not. The vikings have a tactic called the shield wall, where they line up the shields protecting them from arrows and long range weapons, then they advance forward and trample the enemy. They can also form a circle with their shields, blocking any attacks."Ninjas CAN deprive the vikings of there senses"That is if they can get past the shield blockade.Conclusion5 ninjas would not defeat 5 vikings.SourcesDo realize many of my opponent's sources are invalid.
