Not the same level of network centric operation, differing from cloud to soil.
Separated C4I in each branch of armed force is nothing a big deal nowadays, only the doorstep standard to modern warfares.
But still most countries in the world are far from this level, and countries clearly qualified are easy to figure out:
0) United States, matured system and ahead of anyone in developing on a higher stage;
1) France with both independant system and NATO system;
2) Other NATO countries and intimate US allies such as Israel, Japan, Korea, Taiwan, Singapore, are all supported by US system to different degrees;
3) Russia, developed from grand heritage from Red Empire;
4) India, anymore information is welcomed;
5) South Africa or some other developed countries in Northen Europe??? No problems in technique;
6) China, basic bones constructed;
PLA's doctrine is aimed to set a whole network including all weapon platforms and resources. When a war breaks, units from information, space, air, water/underwater, land, nuclear will be all integrated as one to counter US's integrated system (still on construction yet) in the future. Compared with the 2nd rank project J20 (No.X in Earth_Door projects) publicly shown everywhere, only projects as the so called "system" (No.X in Heaven_Door projects) are important enough to be identified as the 1st rank in PLA's big plan.
