by Monty from Think DefenceMy view remains pretty much unchanged
If we intend to fight expeditionary wars, we need expeditionary equipment.
That means we need serious stuff, like Challies and Chally Derived Section Transports and the assault ships and fast landers to land them.
But it also means we need light weight equipment that can get anywhere, either under its own power or by heavy lift helicopter, CH53K tops 15tons of payload, to a 12t vehicle is easy.
Concept D would be my choice, protected against any infantry arms short of anti tank weapons, a 20mm cannon for some quite impressive firepower and a couple of Javelins incase the unexpected happens and it does get a shot at something heavy, or merely needs to blow open a serious strong point.
But I think we can do better than that....
Why just the one?
I think an enclosed APC for even a fireteam is probably pushing it a bit.
However, I dont see any reason we couldnt replicate most of the CVR(T) roles.
A direct fire, or two even, 20mm and two javelins is a fair bit of firepower, but using the same basic hull, is it really that hard to fit a 40mm cannon in some of them?
Indirect Fire, 120mm mortar? Possibly turreted, but even if its just bolted on, thats quite a bit of fire support.
Stores Carrier? You'd (probably) need a front mounted engine, but the vehicle looks like it could carry a pallet, maybe two, on an austere DROPS system.
And, well, I suppose in an emergency, a fireteam could crouch down in the back....
Now, dont get me wrong, these are empaticaly not designed to take on tanks. They are designed to take on light infantry who didnt expect to face armour, and so didnt bother to bring along anti tank weapons, dont laugh, it happens.
Sometimes the weapons issued simply arent front line (like what happened to Task Force Smith), although this is the least likelyas it was front line armour they faced.
The Indians rolled up a Pakistani Army as part of the Ladakh campaign in 1948, they disassembled about half a dozen stuart tanks, carried them up a mountain, rebuilt them, drove through every defensive position the Pakistani Army could raise against them. They simply didnt think to take even medium anti tank weapons up into the mountains, and so had little recourse but to retreat against even cautiously used armour.
Even later, we have the Falklands, I've read several papers as to how useful the CVR(T) was in the Falklands. At Goosegreen, they werent used, and the Paras suffered 81 casualties, at Wireless ridge it was used, and the Paras suffered 14 casualties, at Mt Tumbledown, they were rendered ineffective by a minefield, and the attacking force suffered 63 casualties.
Now, I dont expect any to believe these are an "I win" button, they are however supremely effective tools.
