The Alternative to the IFV strategy.
Boxers and Wiesels
The Boxer, as used by the Germans, is an armoured bus, a troop transporter for the dismount infantry. Its main armament is an RWS with either a 12.7mm HMG or a 40mm GMG. These are for close protection of the vehicle only.
The Battalion's heavy weapons are carried separately in the Wiesel. Many on this site have commented on the Wiesel before, a light, air and helitransportable tracked vehicle that carries a variety of weapons. The principal weapons pairing is a Wiesel with an ATGM (currently the venerable TOW) and another Wiesel with a dual feed 20 mm autocannon. The Wiesel is also used for a mounted 120mm mortar system, a light anti-aircraft system and assorted FOVs, CPs and sensors. These can accompany the troops on deployment by air even when their Boxers can't.
The 20mm/ATGM pairing deserves some further consideration.
The Javelin/NLAW ATGMs have been getting lots of good press in Ukraine but as the war drags on stocks are under stress. That has prompted the Ukrainians to build a 14.5 mm Anti-Materiel Rifle with a 2 km range to take the load off the ATGMs. In much the same way I fancy the 20mm takes the load off of the TOWs in the German Wiesels.
