So , let's take a look at TL8, with some liberties taken as you will see.
Infantry equipment - The assault rifle remains standard, but is supplemented by the laser carbine. The laser carbine has limited weapons potential, but is used primarily as a target designator and range finder. Ballistic cloth flak jackets are in universal use, with whole body cloth armour equipping front line infantry.
In-helmet communications, light amplification, and passive IR detection equipment are available, although not in universal use. Electronic sights are common on infantry assault rifles.
Infantry support - The RAM grenade replaces the early grenade launcher and most specialized anti-tank grenade launchers. Mortars are now capable of firing cluster bomblet rounds. The tac missile's guidance system now requires that the operator track only the target, not that he guide
the missile. Advanced forms of the tac missile incorporate laser target designation. Tac missiles now range up to 5 kilometers and incorporate follow-up IR sensors to achieve successive hits on composite armor as well as their own teleguidance.
Man-portable air defense missiles now have an effective range of 4 kilometers and a head-on engagement capability. Remotely piloted drones provide sensor capabilities and can be equipped with the equivalent of mortar rounds or RAM grenades.
Artillery - Weapons of 15 cm and larger can now deliver tactical nuclear devices, and guided rounds are available which home on laser painted targets. Towards the end of the period, teleguided munitions are introduced. The first computer fire control system is introduced with remote terminals placed with forward observers to speed response time and flexibility. Air defense artillery now includes man portable air defense missiles, some are heat seekers. Larger air defense missiles are more compact and lethal, and are available for forward area defense on selfpropelled chassis. Rapid fire radar directed auto-cannons provide most point defense.
Vehicles - Both horizontal and vertical stabilization are in use allowing firing of main armament of tanks at speeds up to 40 kph. Top speed for tanks is about 90 kph, with armored cars up to about 120 kph. Tank main armament is in the 10-15 cm range wlth more sophisticated battle computers. Many guns are smooth bores for firing high velocity fin stabilized rounds. Toward the middle of the period the first laser tanks are introduced, mounting a bulky pulse gatling-laser. Ablative anti-laser vehicle armor is available, as are anti-laser aerosols, although the latter are expensive. Most laser tanks mount coaxial auto-cannons to scrub ablative armor off target vehicles, thus limiting the effective range of the laser to that of the auto cannon. Composite armor with a high resistance to penetration is available, although its expense initially limits its use to main battle tanks (MBT).
A special piggy-back HEAP round is capable of achieving multiple hits on the same location, giving a limited composite armor defeating capability, but the primary means of knocking out MBT's becomes direct hits from high caliber HE rounds resulting in crew deaths from concusson.
The air/raft comes into limited military use as a utility transport craft.
So a bit more advanced, with the exception of the air/raft this could be the state of things within a few decades. Drone/robot/AI systems are the main breakthrough Traveller got wrong, and the adoption of individual electronic sights, comms, vision enhancement and AR displays.
There is also the noticeable lack of programable grenade launchers which the Chinese Army already have and the US military are introducing
