In MW:O the units forming a Firebase should have the following qualities:
- Powerful Long-Range Weaponry
- Good Heat Efficiency (allowing for continued suppressive fire)
- Equipment to Aid Targeting (Including BAP and TAG)
While the enemy is pinned by the Firebase, available remaining units should move to perform a Flanking maneuver. These units should have the following qualities:
- Powerful Short and Medium Range Weaponry
- High Speed
- Stealth Equipment (such as ECM)
Once the units in the Flanking have engaged the enemy, the Firebase may want to consider closing distance (to bring more firepower to the battle) or adjust their positions for better arcs of fire (in the case that the enemy decides to engage the Flanking behind cover the Firebase will not be able to continue providing direct fire support for the Flanking).
These maneuvers have three distinct disadvantages:
- The units in the Firebase are essentially locked in position, as they must suppress the enemy and keep their attention. This can leave them vulnerable to suprise counter-flanking maneuvers.
- The units in the Flanking, if spotted before they can reach their optimal engagement range, can be very vulnerable to enemy long-range fire while they attempt to close the distance to their engagement range.
- The division of units between two different groups means that while the flanking is in progress (but has not yet reached engagement range), either group is vulnerable to being swarmed by the enemy. This can be mitigated by choosing flanking routes that will not take an excessive amount of time to execute.
If you can wrangle your team-mates into following your orders, I strongly recommend a Firebase and Flanking maneuver.
