Tsarkar sir - Yes. That was my understanding. UAVs are quite fragile as compared to regular aircraft. Even if you don't bring them down, you can make a big mess of their sensors with a few bullets
Here is an old article about some dept. (private firm?) in Khan trying out various things on smaller UAVs/Drones
Marine Sniper In Helicopter Kills A Drone! Black Dart Results

However, if logistics taskings are high, then the MMG might be removed to save space/weight/crew. Boom mounted 23mm gun pods and 57 mm rockets too are not installed as standard for the same reason.

IMHO however a better bet would be a machine gun in the door.. better chance of hitting a moving target whilst being on a shaky moving platform yourself, especially when you dont have a marksman on board
The IAF didn't have Gaurd back then otherwise one or two Gaurd could have been carried as a sniper.
