[DS] Dirtside Infantry firefight rules question

I have another silly Dirtside II rules question I hope someone can
clear up for me.

The example on page 34 shows a 4 element infantry unit A firing on
a 3 element unit B.  After passing his FIRE EFFECTIVENESS check,
player A designates that A4 (an APSW) shoot at B1 (infantry team)
and A1 (an infantry team) will also shoot at B1.  The example
goes on to say that two chits are drawn for A1 and then three chits
are drawn for A4.

Do you draw all 5 chits at once?  Or do you draw the two chits, read the
result, throw the chits back in the pot, and then draw the three chits?

Thanks.
