up armored Humv kits

Both Bronco and Academy make M-1114 kits, along with Legends making M-1114 and M-1151 conversions for Tamiya M-1026.  The Bronco is more $$ but MUCH MUCH better than the Academy kit.  It really will depend on which variant you wish to build.

A slight correction, Bronco makes two versions of the M1114. 

One is an early M1114.

The other is a later version with FRAG 5 doors,  Duke antenna, IBIS Tek push bumper, and Rhino anti-IED device.

Academy makes an M1151.

There is also an M1165 conversion kit from DCorporation out of Korea.

As noted, Legend and Mig do resin conversion kits too, but in my opinion, they are not worth it with the recent plastic kits of them.

is there an uparmored marine variant or r these unversial

They are universal.  The only major difference a USMC vehicle may have is the extended exhaust pipe, but not all do.

USMC M1167 TOW (M1151 w/TOW system) with extended exhaust pipe.

I'd love to do an m1114, painted like mine from 2005, but the kits are a bit rich for my blood right now. Some nice choices though.
