Official word from FOG is that the 12/22 Prep for COSTA Day will be similar to prior FOG SkillBuilders, but at a higher tempo.
This basically means that you should have at least one level 1 pistol course and a level 1 rifle course before signing up online here (http://falconops.net/schedule/
) or email firstname.lastname@example.org
with experience questions.
Skill builders are typically 2 sessions in 1 day, AM pistol and PM carbine. I am guessing you will need about 300 rounds of each type, and maybe more to be safe.
