The Samurai Infantry is the primary and the only infantry remaining of the Division 6.
Since the soldiers have been trained by the Samurai Army to never flee the battlefield and to fight their enemy until their last breath, they will act far differently than the other human enemies. They will use different kind of weapons that are still functional after several years (like swords and bombs). They are pretty crafty opponents; they can drop down from the ceiling to surprise the player, toss bombs from a higher platform to hit the player where they can't, using dynamite when they know they are near death and other tactics. It's very easy to deal with a few regular soldiers, but when the Japanese Assault Forces kick in, it can become one of the hardest moment in the game.
Due to their stay of almost 2 years in the hideout, the soldiers were lacking the materials to produce clothing, leaving them with almost nothing to wear: common WWll Japanese caps with neck flaps, shorts held up with a cord, two bracelets on their wrists and one-strap self-made sandals. They all have beards and long hair and do not wear any vests, coats or shirts. They are also all carrying swords (except the soldiers in the Samurai Tank and the Samurai Plane).
Samurai Soldier: Soldiers with the abilities of a Sword and Bomb soldier. Only one soldier is part of this group, who is the first soldier of the Samurai Army to be seen in the hideout.
Sword Soldier: These soldiers have two attacks: 1) they will slowly shuffle near the player and will pull out their Sword for a quick attack. Once their attack done, they will put their sword back in it's sheath. 2) they will pull out their sword, run up to the player to attack them and will afterward put it back in it's sheath. They are the most common soldiers in the Samurai Army. These soldiers, along with the Bomb Soldiers, reappears in Metal Slug Advance.
Banzai Soldier: The most determined soldiers. They will shuffle a bit with their sword raised, run up to the player and will quickly attack them with their sword without putting it back in it's sheath. They will not stop following the player after spotting them.
Bomb Soldier: These soldiers are equipped with bombs that seem to be hidden somewhere in their pants. When they spot the player, they will attempt to launch the bomb towards the him/her. They have a limited stock of bombs, and if they run out of them, they will simply stay idle and will oddly not harm the player with their sword if he/she is too close. These soldiers, along with the Sword Soldiers, reappears in Metal Slug Advance, but can now jump to slightly move.
Guard Soldier: These uncommon soldiers are found near prisoners, entrances and supplies. They are stationary and will use their sword to defend themselves and what they are defending.
Japanese Assault Force: A variant of the Sword and the Guard Soldiers wearing red clothes. When hit, they will take out a stick of dynamite, killing themselves and the player character if he/she is close enough. They can also drop down from the ceiling of their hideout for a surprise attack. When attacking with a Samurai Tank, they will Kamikaze themselves after they tried to attack the player once.
The soldiers have a bunch of unused animations in the Metal Slug 3 Data. Each frames can be found here.
- The Banzai Soldier is the fastest attacking enemy in the whole series: 2 slashes with its sword per second.
- They are the enemies with the highest number of burning animations.
- They are also the only enemies other than the Man Eater with proper "falling while burning" animations.
- They are the fastest moving human enemy, due to their extremely light-weighted equipment.
- Judging from the Metal Slug Attack descriptions, the soldiers use Katanas.
- Though the fact that they were used in wars suggest that they were actually Guntōs.
- The bombs from the Bomb Infantry are based on the Type 4 Grenade.
- Unlike the others human enemies, the soldiers will never flee the player.
- In Metal Slug Advance, the soldiers will all perform a Kamikaze upon death, regardless their uniforms.
