What type of infantry is the most basic?

Answer 1

I suppose light infantry, although not so much anymore, especially as the wars in Iraq and Afghanistan have required them to adapt to mechanised operations. Currently, the US Army only has two distinct types of infantry - those who operate mortars, and those who don't.

Prior to 2002, there were four main infantry MOS - 11B (light infantry), 11C (mortars), 11H (TOW anti-tank), and 11M (mechanised). 11H and 11M were folded into 11B, so there is no longer any distinction made between mechanised infantry soldiers and light infantry soldiers.

Answer 2

The most basic type of infantry is typically the standard infantry or rifleman. They serve as the backbone of an infantry unit and are trained in basic combat skills, such as marksmanship, patrolling, and maneuvering in various terrains. They are equipped with rifles and are responsible for engaging in direct combat with the enemy.
