eh, CAMP is difficult la in TDM - once you camp, there's kill cam. guarantee the fella will go back to find you if respawn nearby. if not also UAV will show your location (let's not talk using cold-blood)

my killstreak highest also 5. usually 3. best way is to know the map, and know what gun suits your play style for the map.

btw as what others say - look at map, if you see your team mate around means no enemy around. if team mate nearby suddenly go missing means the fella kena liao, you could be next.

don't run around like headless chicken. run around must have a purpose. best to sprint short distance, hide, observe, then move again. use the gun fire also to help hear footsteps or people exchanging fire.

learn to use cover. ehh what else ah? LOL. talk like pro but not pro yet, i reach KDR 1:1 also very happy liao.
