I gave all 25 maps a quick test on my Server, using my usual Custom-game setup.
But I think most of these maps are designed for normal Conquest or Co-op game-modes (Humans Vs Bots).
Some of the maps worked, some loaded ok but had major graphics errors and the rest caused my BFV to CTD! (Crash To Desktop).

1: Agent_Orange - Worked, but was a bit crap.
2: An_Loc_Ambush - Failed, CTD.
3: Ap_Bac - Worked, again a bit crap.
4: Battle_of_Dong_Ha - Failed, CTD.
5: Con_Dao_Islands - Failed, CTD.
6: Da_Nang_Standoff - Worked, not-bad, has potential.
7: Da_Nang_Sunset - Fail, loaded but Graphics were messed-up.
8: Defence_of_Pleiku - Worked, crap, green-fog wtf.
9: Firebase_Whiskey - Worked, quite good.
10: Gulf_of_Tonkin - Failed, CTD.
11: Junction_City - Worked, Awesome, wish they were all like this.
12: Kontum_Crossing - Worked, good but Red gets all the Aircraft.
13: Linebacker - Worked, good but again unbalanced in-favour of Red.
14: Lz_X_Ray - Fail, loaded but Graphics were messed-up.
15: Lz_X_Ray_Night - Worked, but again a bit crap.
16: Mekong_Monsoon - Worked, and again a bit crap.
17: Mekong_River - Failed, CTD.
18: Night_Patrol - Failed, CTD.
19: Operation_White_Star - Worked, looks good but would be crap to play.
20: Raid_on_Koh_Tral - Fail, loaded but Graphics were messed-up.
21: Red_River_Raid - Failed, CTD.
22: Rolling_Thunder - Failed, CTD.
23: Saigon_Nights - Worked, very good but not as good as J-City.
24: Steel_Tiger - Failed, CTD.
25: Tet_Offensive - Worked, very good but not as good as J-City.

If anyone wants to do a more in-depth review, please do
I'm sure some of the maps that failed for me will work in other game-modes.

I went back and had another play-around on the 'Junction_City' map last night... Wow! ...it's such a good map, it's worth downloading and installing the whole 25 maps - just for that 1 map

It's so good,
I played it with HueyBob ( Bob ) and Penut,
One bad thing is,.. if you have 2 people playing you can search for years. we need 10 at least to make it nice..

SO DOWNLOAD GUYS !!
