Best order to get gear:

  1. Eye protection, obvious reasons.
  2. Combat pants, they've got large pockets that you can store your mags in until you get a load bearing vest or chest rig.
  3. Combat shirt, adds to the authenticity of your load out if they're the same pattern as your combat pants.
  4. Combat boots or really good hiking boots with high ankle coverage, I can't tell you how many times I've seen airsofters and paintballers fuck up their ankles because they weren't wearing proper footwear.
  5. Holster if you have a sidearm that you want to game every game. If no sidearm, skip this.
  6. Vest or chest rig, something to hold your magazines, MOLLE is by far the best to go with since you can customize it for fairly cheap to suit what you need.
  7. Gloves, very handy (pun intended) when playing outdoors or in very close CQB. Prevents lots of painful hand/finger shots.
  8. Helmet/Headwear, something that compliments your eye protection and combats.
  9. Extra bits like shemagh's and radios, etc, etc...
