The PA has analogous solutions for each:
1. Javelin ATGM: There's been a standard ATGM program in the works. But it was tied to the new attack helicopter program. For example, when it ordered the T129 ATAK, the PA also planned to induct large numbers of Roketsan OMTAS and UMTAS for use from aircraft, infantry, and vehicles. They'll likely buy smaller batches of ATGMs until the attack helicopter programs come online. Once they do, they'll standardize on an ATGM for service-wide induction.
2. NLAW: The PA uses the Alcotán-100.
3. HIMARS: The PA doesn't have an exact solution like the HIMARS, but it does have guided rocket capabilities in the 122 mm and 300 mm calibers. The next ideal step would be to develop a hot-swappable module for our existing guided rockets.
4. Artillery/drone coordination: The PA can probably do it with its existing solutions, but IIRC there are no dedicated solutions for this.
