In the last post I considered the organization of the garrison of the temple of the frog as a model for small garrisons and troops in OD&D, and I listed the arms and equipment given in the text.  It's fine to simply use that, but if you (like me) would prefer a little variety in arms and equipment, there is a really terrific series of tables in Arneson's rulebook 1 of Adventures in Fantasy, page 31, that will give you just that.
I've broken apart the tables on that page for ease of organization, switched the figures from % to d20, and edited some of the instructions so as to make the whole thing more user friendly.  Here it is:
