On your request i have made 26 scripts each for 1 vehicle. Just download them and follow instructions on how to execute scripts (spawn the vehicles). There are some on this forum just look for them.
And of course don't forget to thanks me.

I got a fix for your problems here!!!
Don't use a script executor on these scripts. Use Cheat Engine (latest version):
First, you want to navigate to your ArmA 2: Operation Arrowhead directory and create a folder there called "scripts" and put my Vehicle Scripts in it.
Open up Cheat Engine and ArmA II: CO. At the main menu of ArmA II: CO, you want to go to cheat engine and find the process "arma2oa.exe". Once you have selected this, you want to change the value type to "String" and search for:
private ["_dummy"]; _dummy = [_this,"onload"] execVM "\ca\ui\scripts\dedicatedServerInterface.sqf";
Once you find the value, double click it to add it to the window at the bottom and double click the value to edit it to:
private ["_dummy"]; _dummy = [_this,"onload"] execVM "\scripts\[nameofvehicleyouwanttospawn].sqf";
Head back in game and press Right Shift + P and around 10 meters behind you should spawn whatever vehicle you picked.
Note: You need a Shift+P enabled server.
