1. Get a buff from the nearest draenei statue. If you follow the road out of the garrison towards the draenei village, you will find one of the statues on the left side of the road.
2. Assign a follower with bodyguard ability to your level 2-3 barracks. Take the follower on patrol with you. Talk to another random follower and ask him or her to go on patrol with you. This one cannot leave your garrison but still can be useful.
3. If you are the owner of the garrison that will be invaded, get special buff flasks (three in total, one of each kind) from the dwarf lady in your town hall. Those flasks apparently are not clickable if you are just helping out a friend with an invasion.
4. Put one melee friend at the main gate of the invaded garrison. Mobs over there are rather condensed. Good for a melee.
5. Kill stuff.
