Assuming that you have tactical insertion equipped, you have to press and hold the "throw special grenade" button on your controller until the tactical insertion flare is lit. Once the flare is lit, you can let go of the "throw special grenade" button. Wherever you are standing when you let go of the "throw special grenade" button, is where you will drop you tactical insertion.
One person lays down a tactical insertion right in front of you in a secluded area. And you kill them and keep repeating. This usually occurs in a Free for All or Barebones.
He makes his friend put a tactical insertion down.
Boosters are when two people in Modern Warfare 2 who know each other and decided to boost in large maps where they will not get caught doing it. Boosting is when two people on opposite teams boost in a place on a map where they will not be found. One place a tactical insertion down and the other person kills them. Then, the person who died before keeps putting down a tactical insertion so they will spawn there and get killed by the other person. This tactic is mainly used by noobs who want to get high kill streaks such as a chopper gunner, ac-130, emp, or a nuke.
it will probably go down when modern warfare 3 comes out
The only way to boost in Modern Warfare 2 would be to rank up in levels and unlock certain Perks to aid you during game. Another way to boost in Modern Warfare 2: say you want to boost a nuke, what you do is you have a friend on the other team with a tactical insertion and both of you go into a secluded spot and the person with the insertion puts it down and lets the other person kill them and he will re-spawn in the same spot and you repeat this until you have the nuke. It works with other things like getting a care package or getting lots of headshots or kills. you could also go into a barebones match and just get headshots the thing is in barebones you dont get killstreak reward but if you have a group of 4 you can hold the x key to lock the loby and it will only be you 4 in 1 match
