yes, and they will...more then needed or necessary in the add-on...
BUT...if you think about it, if you want realism then few weapons is more accurate...
99% of the US SWAT teams carry a sidearm, and one of the following three weapons (besides the sniper of course)...
MP5... (very few with the new MP7)
M4 (maybe M16 for the cheaper departments, gov't surplus.)
G36 (rare)
and a shotgun man.
PS... this was my 911 poste.
