Help with last 4 achievements please

Hi, I’m obsessed with getting all the gamerscore on halo reach but just can’t seem to find enough players in certain game types, or the game types rarely come up etc. So would anyone be willing to help me get them, you will need all the map packs.
The achievements are:

Don’t Touch That!
Defiant: Prevent the attacking team from touching the flag in a matchmade 1-Flag CTF game.
25

Paper Beats Rock
Defiant: Assassinate a player that just exited Armor-Lock in a matchmade game.
15

All Alone
Defiant: Be the last surviving uninfected player in a matchmade Infection game.
10

Bounty Hunter
Anniversary: Capture 10 skulls at once in a matchmade Headhunter game.
75
