Ok. Tested new version. I'm a bit dissapointed.
You added 3xt55 near first village. And one or two bmp more. Now it's a bit hard to finish mission but.... gameplay it's still the same. You can fail only if someone from Your Ai teammates will shoot to T-55 (they suck with javelin and law to...). Otherwise mission is exactly as the original version. It's nice that You added few infantry but there is a few bugs which I spotted:
-Infantry in 1st village are blocked few times by buildings.
-When You provoke t-55's to follow You to base challenger don't shoot to them
-Vulcan in base don't shooting to Hind's
Maybe it's fault of my version 1.99. But it's better to say You.
