Details on the satellite's payload are still contradicting.
Is the payload just 2*L, 19*Ku, 12*Ka band transponders, or is it UHF, X, Ku, Ka, EHF band.
And no footprint found at all!

If there is any kind of military aplication of AlComSat-1 communications payload, I wouldn't expect any public information about it.

Ku, Ka as well as military bands on board were first mentionned in the unofficial site menadefense in September 2016.
In its publication soon after launch, CGWIC mentionned only, as you said, 19Ku, 12Ka and 2L (these 2 presumably for the Xinhua referenced GPS augmentation service).
As for footprints, ASAL mentions "couverture nationale  et régionale (Afrique du nord et Sahel)"

I don't remember now where I've read it, some of the services provided by the new satellite will be used on the fight of Polisario Front with Morocco. So, I firmly believe that the military bands are onboard AlComSat-1 communications satellite.

Successful fixed-point

2017年12月18日20时45分,经过8天紧张有序的飞行控制工作,阿尔及利亚一号通信卫星历经5次变轨、3次定点捕获,成功定点于地球静止轨道西经24.8°,为后续投入运营打下坚实基础。中阿双方在西安卫星测控中心共同见证了这一历史时刻。

English translation:

At 2045 hours [Beijing Time] on 18 December 2017, after eight days of intense and orderly flight control task during which Alcomsat-1 has undergone 5 orbital changes and 3 final orbit acquisition maneuvers, the satellite was successfully located at 24.8 ° west longitude in the geostationary orbit, laying a solid foundation for subsequent operation. Both Chinese and Algerian parties together witnessed this historic moment in Xi'an Satellite Control Center.

This latest technology satellite will allow gathering the favorite TV channels of Algerians on a single satellite, instead of switching between two satellites (Nilesat and Astra)
