- Machine guns should be sited so the maximum number of targets can be engaged, continuous fire can be delivered, and likely routes of approach are covered.
- Machine guns used to defend march columns should be interspersed in the convoy, with emphasis on the lead and rear elements. (See figure F-16.)
