Wrong .. Ur Wrong About Everything..
Pave-low will count toward ur kill streak if u dont have a chopper or ac130..
for example kill streaks.. 3, 9, 15, try it.. or nuke
also it does not matter for the sentry if its a normal care package or sentry care package. it will count even if u have 100 deaths. doesnt matter.
DOES NOT HAVE TO BE 1ST IN THE GAME!!
