The US Army uses a technique called "bounding overwatch".
A light infantry squad is made up of two fire teams. One fire team provides 'overwatch' (covering fire) while the other uses cover and concealment to move to the next overwatch position, then the team previously in overwatch bounds past them and the previously bounding team takes up overwatch.
During movement, one formation used is a 'wedge' (arrowhead). The squad leader places himself so as to best control fire and movement if contact is initiated.
Platoons move by bounding squads. Companies
can move by bounding platoons.
Mechanized units use the same process, and it can be done with dismounted and mounted elements (the Bradleys would usually provide the overwatch while the dismounted infantry manuevers).
