This was my advice to others from page 202, post# 2014
(copy paste of the hicks section. I did this for each)
For Hicks
-Replace Hands (or use natural hands when getting new body). He didnt wear gloves.
-Drill out the 'hole' where "Born again" is painted on his left shoulder bell
-Write "Non Toxic" over his codpiece on his ab-plate in gray
-Write his solcial security number across his upper arm (his tattoo)
-Paint "LIFER" in white between the lower brackets on his back
-Paint the red 'kanji' above "LIFER"
-Get a tan helmet band
-Attach a chin strap and tuck the bits under his helmet band (so they are pulled tight out of the way)
-Replace the cartoon style 870 shotgun he came with. (Ideally use a modded full size 21C toys Ithaca 37, but a 'stakeout' Ithaca 37 works in a pinch)
-Hicks has only 1 pouch! Ditch the 2 small ones. He only had the one big one over his left buttocks.
-Find 1 'belt tool' for his right pelvis area (from the smartgunner sets, incorrectly given to them as 'batteries').
-Run 3 grenades in right strap if going for the middle/later movie effect. 4 grenades for a "pre-crap-hits-the-fan" look.
-Give him a white wrist band or tape on his right wrist
-Get rid of the fancy webbing on the hand welder. He actually just had it tied to his belt with paracord (with a loop the window was tucked into and dangling from)
In addition to those relatively easy fixes, more advanced stuff:
-yes replace the knife with a small boot knife that has a leather sheath.
-get an undershirt/tshirt on him, cut the sleeves of the BDU shorter and roll them real tight up into the tshirt.
-wash the BDUs in a white acrylic mix to tone down the colors and make them look worn. I think for the stock 'yellow' BDUs i even added some blue. A faded green tint is not completely accurate, but looks a lot better than bright yellow.
-Try to add a brown leather rectangular lighter to his right strap above his grenades (or something that implies it might be a lighter)
-Repaint the armor if you are feeling ballsy. At minimum do something to get rid of the neon swatches and darken it up.
As for a headset, this was my solution. Overall don't worry about messing up his hair. In the film he either had a helmet on (hive battle) or he had the headset on. Unless you are doing a 'breifing' or 'breakfast' hicks, he never had fancy hair with nothing smashing it down.
I drilled/carved out the temples to insert a headset. When his helmet was on, you couldn't see the holes and when the helmet was off, i inserted the headset bits. Overall I am very pleased.
