Go to the Army Electronic Library
http://armyapp.dnd.ca/ael/database_base_de_donnees.asp
..and in the "Publication Search," click on "Book Title," and type "Infantry". This will bring up a list of relevant pubs, several of which are online, that you can cut & paste into PowerPoint for your troops.
Perhaps needless to say (Murphy, of Murphy's Law fame, was a soldier)....neither Infantry: Vol 3: Inf Sect and Pl in Battle, nor the Sect/Pl Comd Aide-Memoire are online. For these, and other pubs not online, your unit Ops/Trg office should have them.
If you want to include some "big picture" stuff to set the stage: Land Force Tactical Doctrine

To make pretty (us infantry types have short attention spans), go to Combat Camera
