A selam Brother, a nice system,would be also effective in ground role ! But I have never heard and read about this or any other mobile AA Gun System in service with thePakistan army nowdays,maybe it does not fit in their air defence/Artillery doctrine ?
Besides that my argument was to use the local products, industry and systems which are already in service, this were the
Type 65/74 AA (ca. 1000 and more stored in reserve) guns and the local produced HINO trucks.
Type 74
The Type 74 is an improved variant of the Type 65 introduced in 1974. The weapon share the same 37mm cannon and ammunitions as the Type 65, but can be operated either manually or remotely by the fire-control unit consisting of an electro-optical director and a target searching radar. This enables the weapon to operate under day/night, all-weather conditions.
Hino PAK Truck:
View attachment 330222
The SP AD regiments in Armoured formations use Anza on Talha.
The infantry formations tow AD guns behind trucks and then deploy them using camouflage.
The reasons for towing and not actually mounting the AA gun on truck could be:
1. Truck gets engaged with gun and cannot be used for transport or cargo. Cannot be used for any other duty.
2. A mobile AA platform may not be required. Infantry job is securing and holding a position.
3. Most AD assets are deployed at fixed sensitive locations like airfields etc
Since you mentioned use of leather cover/planne, i think you mean tarpaulin (or "Tarpaal" in local language) ?
Tarpaulin is already used on AD guns towed behind trucks during transit/convoys for secrecy and saving them from weather effects.
The deployment of AD Regiments is expected to be a mix of MANPADS and AAA, with the SAMs forming the outer ring. The AD regiments could be of two types:
1. Equipped with:- 4 X 35mm twin Oerlikon guns with sky guard radar + 8 x RBS -70/Anza SAMs with Giraffe radar.
2. Equipped with:- 6 X 37 mm AA Guns and 6 X 14.5 mm Quad A-A Guns + 8 X RBS-70/Anza with Giraffe radar.
The nasty surprise that you are mentioning can also be given by SAM's, requires a launcher and a few missiles. Easily portable and deploy-able within seconds from fixed position to Mobile (like on a truck or Jeep).
However, If the AA guns are mounted on a truck, they can also provide massive firepower to support infantry using heavy calibre like 35mm or 40mm, which could rip off light vehicles like jeeps/trucks easily and damage IA BMP's.
The HINO truck you have shown seems to be HINO 500 series with 7600cc engine and 251 bhp with GVW 18000 KG.
Weight of 37mm twin barrel gun is 3400 KG
Weight of 40mm gun is 1900 KG
Weight of 35mm twin barrel gun is 6700 KG
The weight becomes double with ammunition included. I think the picture you provided is a twin barrelled 23mm Gun? You can have an idea how much mobility of truck can be affected by installing 35mm, 37mm or 40mm gun.
Range of 35mm Gun = 4 km
Range of 37mm Gun = 7-8 km
Range of 40 mm Gun = 7 km
The 37mm gun has low rate of fire so its paired with 14.5mm gun which has high rate of fire.
Radar increases effectiveness of AD warfare, since Pakistan AD regiments use GIRAFFE/SkyGuard radars, which have remote(wireless) connectivity. So a mobile AA platform like you have mentioned can be used with Radars too.
Sky Guard.
The SkyGuard system uses encrypted radio-waves so its wireless connectivity can be upto 500m. It can control 2 X 35mm Guns and 2 X 8-Cell SAM launchers simultaneously. The search radar can scan an area up to 20 km and locks on the target at 14.5 km. The radar can track one target at a time and provide data to two to three guns. An additional TV camera enables aircraft recognition. The system can be employed both against aerial and ground targets.
GIRAFFE.
The radar is designed to detect very low flying targets and is linked with a number of firing units for precision target designation. The radar has a range of 40 kms in surveillance mode and is reduced to 20 kms in designation mode.
