One constant that I run into with students that have already survived these kinds of things, is that there is hardly ever any time to "seek cover, get off the center line, throw up a styalized block, etc" the opening ceremony hardly allows time for that, now IF it continues past that point it DOES get dynamic, and fast, but in the words of a famous gun fighter...while I was seeking cover the basta#d shot me in the a$#, so I turned around and decked him with half a mag. Once it is time to shoot, don't flop drop roll, get to fast accurate shooting, if you can do that while moving great, but where did we learn that???..... well right back to competition.
