Infantry and Tanks
Infantry and Tanks (センシャ＆ホヘイ, Tanks & Infantry) is an Assist Trophy in Super Smash Bros. Brawl and Super Smash Bros. 4, taken from the Nintendo Wars series. They form the bulk of the player's fighting force in every game in which they appear. They were first confirmed as an Assist Trophy in a gameplay video from Nintendo, but were later confirmed on 14th March 2008 on the Smash Bros. DOJO!!.
Infantry and Tanks are the basic attack units seen in all Nintendo Wars games. The ones seen in Brawl are red, which is one of the four colors which are given to a player based on player order (1st player - red, 2nd player - blue, 3rd player - green, 4th - yellow). Infantry have the least amount of power and have low mobility, but are useful in that they can capture enemy bases and conquer buildings. Tanks have more power than infanty, and their mobility is considerably higher, are weaker compared to other vehicles, such as the Medium Tank and Artillery. Advance Wars, Advance Wars 2, and Advance Wars: Dual Strike all use the same sprites for each unit.
As an Assist Trophy
Infantry & Tanks is one of six Assist Trophies that needs to be unlocked before it can be used. Upon being unleashed from the trophy, GBA sprites of Soldiers and Tanks will emerge, shooting bullets and missiles, which will damage any opposing players. While the soldiers and tanks are marching around, an air-raid siren will sound. Much like Excitebikes and Lakitu & Spinies, this Assist Trophy is represented by actual sprites from a game they appeared in other than Brawl.
How to Unlock
Play a total of 300 matches of Brawls or related modes.
Units first introduced in Famicom Wars, where they fight battles against enemy forces. Infantry are the least expensive to deploy of all units. They're not too strong, but they move well and can capture property. There are two tank types: tank A, which is expensive but has good mobility and firepower, and tank B which is cheaper but can change battles with sheer numbers.
As an Assist Trophy
The Infantry and Tanks return as an Assist Trophy and are functionally the same as in Brawl, however they are now available from the start of the game.
Infantry and Tanks do not return as an Assist Trophy. They do however have a Spirit.
