What's your CO build on one of the few Marine vs. Marine maps?

Usually, I go:

Weapons 1
Shotgun
Weapons 2
HMG
Resupply
Weapons 3
Motion Tracking
Armor 1
Armor 2

I take it MT actually works pretty nicely?
I haven't decided on upgrade path yet. Usually get resupply and GL asap...

any links for the lazy? to the maps I mean

I always get resupply first; medpacks are far more effective against marines than against aliens. After that, I usually go for as much damage as possible. I rarely bother to upgrade my armor unless I'm getting a jetpack, as armor tends to get worn down very quickly. I usually also a welder to weld teammates; unfortunately I am often the only person to do this.

Bah, don't weld, its not fair. Green team can't weld anything, so Blue team has too much of an advantage with welders.

I just go for pure damage - but resupply first. Your armor will dissapear so fast that it's not worth getting ups for.

So that would be

Resupply
Weapon 1
Shotty
Hmg
Weapon 2
Weapon 3
Motion tracking

And then toys!!

W1 Pistol is already deadly, and I haven't noticed any life longevity with armor.
SG Instagib pretty much.
A1
A2
JP JPs are gods in the right hands.
HMG GLs are great, but HMGs bring the PAIN!
resupply A god still takes damage...
Hand grenade or some other little toy... HGs are good because mariens are slow moving and still get hit by them, not to mention I can throw one into the comm area for some nice damage. I don't have trouble identifying enemies as that I shoot a shot or two with my pistol at long ranges before the name box pops up. Been a few times I followed a couple of guys out of their base, they turned around, saw me, and turned back around and kept running to our base. Killed them with pistol shots.

The Mower:

level 2: motion
level 3: resupply
level 4: w1
level 5: shotty
level 6: hmg\gl
level 7: cat packs[if hmg], otherwise w2.
level 8: w2 [or w3]
level 9: w3 [or a1]
level 10: a1 [or a2]

you would not belive the strength of a cat pack level 3 hmg vs's anything marine.

Death From Above:

2: motion
3: resupply
4: w1
5: shotty
6: gl or hmg
7: a1
8: a2
10: jp

I highly recommend rushing MT so you know who to shoot.

OMG...its marine vs marine...come on guys... plz tell me...Is the AK better? or the M4A1? im really interested...
Do you buy smoke grens for your Marines? How many shots does a Glock need to destroy the CC?

k no more of the "I hate MvsM stuff"...
