Concept:Pontoon and platoon are two distinct terms: one relates to a floating structure used as a bridge, while the other is a military unit of soldiers.
Explanation:A pontoon is a floating platform or hollow structure used to support a temporary bridge over water.
Thus, pontoon is commonly understood as a temporary bridge.
A platoon is a small military formation, typically a group of soldiers commanded by a junior officer.
So platoon clearly refers to a group of soldiers.
