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 direct combat ground units seen in all Nintendo Wars games. Infantry have the least amount of power and low mobility, but can capture enemy properties. Tanks have more power and mobility than Infantry, but are weaker than other vehicles such as the Medium Tank and Artillery.
The Assist Trophy's units are part of the Orange Star army, evident by their titular coloration. Their appearance is based on the map sprites used in Advance Wars, Advance Wars 2: Black Hole Rising, and Advance Wars: Dual Strike.
As an Assist Trophy
Infantry & Tanks is one of six Assist Trophies that needs to be unlocked before it can be used. When summoned, the units emerge and fire 3D bullets and missiles, which will damage any opposing players. While the Assist Trophy is active, an air raid siren will sound. Much like Excitebikes and Lakitu & Spinies, this Assist Trophy is represented by 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.
