Strategic Info Against - Most opponents use Service Pods to repair and rearm in a pinch. Because of this destroying their Service Pods, since they only take a few hits, can cripple the non-AI player's defense during an assault, letting you destroy them easier. Using - Service Pods are only good for a quick rearm and repair near base. It is wise to keep 5-10 of them at your Recycler for that quick repair when you really need it, otherwise ignore them and use the Dower. Strategic Info Against - When facing these units it is important to know just how fast they are.
Sentries have a tendency to move out of the way when they are being fired upon.
While their dodging may seem like a disadvantage, it can be used as an advantage. When a Sentry moves out of the way they tend to turn, then move, then turn again somewhere else to face you and start firing at you. If you keep your guns trained on them, and fire a bit ahead of them, you should be able to continuously hit them while they keep trying to move out of your firing range. After a few hits you should be able to destroy them. Using - These buggers move fast.
