1. TEAMMATES

Try to gather up a couple friends and communicate to help everyone find out where the enemy team is. From there you can all head towards where they are at and dominate.

2. Flanking

Flanking is a very effective and wise choice to make when playing objective based game types. Flanking is when you go around the outside to catch your enemy off guard.

3. Camping

This isn't a great strategy considering people will get really pissed and hate you but basicly what you do is hide in one corner a catch some random people running around the map. Preferably use claymores/motion sensors ghost perk/ninja use silencer attachment

4. Using Appropriate Killstreaks

Try to use atleast one killstreak that will benefit your team (spy plane, counter spy plane, blackbird) and two that will benefit just you. (dogs etc.)

5. Headset

Using a headset is a wise choice because you can hear enemy footstep from super far away.
